Embodiment Construction

[0035]In the article "New Approach to Quantum Electrodynamics, Progress in Physics, 2, 15-49 (2008)" a new theory of quantum electrodynamics (QED) is disclosed. On the basis of this new quantum electrodynamics theory, by introducing a parameter ih+κ and introducing a transformation Among them, s is the real time (proper time) of relativity, parameter h is Planck's constant, parameter κ≥0 and κ=k B T, where T is the absolute temperature, k B is the Boltzmann constant; statistical physics and quantum physics can then be unified.

[0036] Through the seagull vertex term of this new quantum electrodynamic theory, magnetism and superconductivity can be unified. The seagull apex term is a new quantum electrodynamic effect. This new quantum electrodynamic effect gives the attractive effect of forming Cooper pairs. This new quantum electrodynamic effect gives a unified theory of magnetism including ferromagnetism, antiferromagnetism, paramagnetism and diamagnetism, and it also gi...

Abstract

The invention relates to a high-temperature superconductor. The high-temperature superconductor is an intermetallic compound with the general formula: R1-x'E(1-x'')x'Ax''x'[(Dm(1-x' '')Gmx' '')1-yMy]1+z, wherein m equals to 2 or 5, x' is not smaller than 0 and not greater than 1, x'' is not smaller than 0.01 and not greater than 0.9, x' '' is not smaller than 0 and not greater than 1, y is not smaller than 0 and not greater than 0.02, z is not smaller than 0 and not greater than 0.01, channels of 3d-layer electrons, 3s-layer electrons, 3p-layer electrons, 4s-layer electrons or 4p-layer electrons of the composition D or composition G are in an open state. According to the invention, as the intermetallic compound is of a three-layer hexagonal crystal structure, and the channels of the electrons of the composition D or the composition G are in the open state, the intermetallic compound is the high-temperature superconductor which has a higher critical current density and a critical temperature (Tc) of higher than 300K. The high-temperature superconductor is formed by synthesizing metallics, has a certain flexibility and malleability, and is convenient for production of products of various shapes and structures, thereby greatly increasing industrial application performances.

Description

technical field [0001] The present invention relates to a superconductor, more specifically, to a high-temperature superconductor and a preparation method thereof. Background technique [0002] There is a class of superconductors, called high-temperature superconductors, first described in the article by Bednorz and Muller: "Possible High-Tc Superconductivity in the BaLaCuO System, Zeitschrifi frPhsik, B64, 189 (1986)" disclosure. Since then a variety of such copper oxide (cuprates) superconductors have been discovered. For example, bismuth-based copper oxides with a critical temperature Tc≈105K are described in the article "H. Maeda, et al., J. App. Phys. 27, L209 (1988)" and the US patent "US Patent 7132288, Maeda et al. 1 / 1989" was released. For example, thallium-based copper oxides with a critical temperature Tc≈125K are disclosed in the article "Z.Z. Sheng and A.M. Hermann, Nature, 332, 55 (1988)" and US Patent 5082825 Hermann 8 / 1988. For example, mercury-based copp...
