(2) This refers to the calorific effect due to the coupling of polarized electric dipoles and polarized carriers under the driving of an applied alternating electromagnetic field and the component alternating electric field of the alternating electromagnetic field, and includes not only the electric moment calorific effect due to a single electric moment entropy and the Joule calorific effect due to a single crystal lattice entropy and electron entropy, but also the electric moment-electric conduction coupling calorific effect due to the electric moment-(crystal lattice + electron) coupling entropy. (3) This refers to the calorific effect due to the coupling of polarized electric dipoles and carriers, and magnetized magnetic dipoles, under the action of the applied alternating electromagnetic field and the components of the alternating electromagnetic field. This includes not only the calorific effect of electric moments due to single electric moment entropy, the calorific effect of magnetic moments due to single magnetic moment entropy, and the Joule calorific effect due to single lattice entropy and electron entropy, but also the coupling calorific effect between electric moments and magnetic moments due to electric moment-magnetic moment coupling entropy, the coupling calorific effect between electric moments and electrical conduction due to electric moment-(crystal lattice + electron) coupling entropy, the coupling calorific effect between magnetic moments and electrical conduction due to magnetic moment-(crystal lattice + electron) coupling entropy, and the coupling calorific effect between electric moments, magnetic moments and electrical conduction due to electric moment-magnetic moment-(crystal lattice + electron) coupling entropy.

[0032] It should be noted that the multicaloric effect is not simply the sum of the single caloric effects of each term, but also includes a multiple correlation coupling term formed by alternately coupling the single caloric effects of each term, which makes the heat dissipation phenomenon more pronounced.

Ultrafine component particles that are slightly soluble in water or contain crystal water, which increase the magnetic hysteresis loss, attenuation loss, and domain wall resonance loss, as well as the radio wave absorption loss of high-density ultrafine particle aggregates, and ultrafine component particles that enhance the intrinsic electric moment orientation polarization and thermal ion relaxation polarization, resulting in high relaxation polarization loss, are mixed and polished sufficiently by a low-temperature solid-phase reaction method to form a cold-molten layer on the particle surface, allowing precipitated ions to diffuse with each other in the cold-molten layer, and as the polishing process continues, new cold-molten layers are constantly formed on the particle surface, so that each cold-molten layer formed on the surface of each particle corresponds to a micro-reaction area, and the generated structures are grown as cores to obtain an electric moment-magnetic moment-electric conductivity coupling heating medium with a coated structure. Furthermore, a colloidal particle dispersion system formed from an ultrafine component that increases the magnetic hysteresis loss, attenuation loss, and magnetic domain wall resonance loss, which enable polycondensation reactions, and also increases the radio wave absorption loss of the high-density ultrafine particle aggregate, and an ultrafine component that enhances the intrinsic electric moment orientation polarization and thermal ion relaxation polarization, thereby resulting in high relaxation polarization loss, may be subjected to dissolution by low-temperature heat treatment and high-temperature sintering on a three-dimensional network structure formed by further aggregation and adhesion of polycondensation reactions by the sol-gel method, thereby obtaining an electric moment-magnetic moment-electric conductivity coupling heating medium with a coating structure.

Alternatively, a porous electric moment-magnetic moment-electric conductivity coupling heating medium may be obtained by sintering a network gel formed from a soluble complex or complex salt obtained by adding a complexing agent to a metal inorganic salt precursor solution and causing a complex reaction with metal ions, using a metal complex gel method, for ultrafine component particles that are insoluble in alcohol, increase the magnetic hysteresis loss, attenuation loss and magnetic domain wall resonance loss, and increase the radio wave absorption loss of the high-density ultrafine particle aggregate; ultrafine component particles that enhance the intrinsic electric moment orientation polarization and thermal ion relaxation polarization, resulting in high relaxation polarization loss; and component particles that increase the carriers such as free electrons, ions, doping defects, and voids.Alternatively, a porous dielectric porous ceramic with high polarization loss may be modified by precipitation using an appropriate amount of precipitant, by using ultrafine component ions in a solution that increase the magnetic hysteresis loss, attenuation loss, and domain wall resonance loss, as well as the radio wave absorption loss of high-density ultrafine particle aggregates, and component ions that increase carriers such as free electrons, ions, doping defects, and voids, thereby forming a composite film layer on the inner surface of the voids consisting of ultrafine components that increase the magnetic hysteresis loss, attenuation loss, and domain wall resonance loss, as well as the radio wave absorption loss of high-density ultrafine particle aggregates, and components that increase carriers such as free electrons, ions, doping defects, and voids. Furthermore, by performing void modification on a dielectric porous ceramic with high polarization loss using a chemical plating method, and reducing the free electrons, ions, doping defects, and metal ions that increase carriers such as voids, adsorbed in the plating solution within the voids, to metal using a reducing agent in the plating solution, and depositing them onto the inner surface of the voids, a porous electrical moment-electrical conduction coupling heating medium can be obtained.
