A method and apparatus is provided for generating an artificial heat sink below ambient temperature for a cryogenic condenser (32) by isothermally magnetizing a paramagnetic fluid and removing the magnetic field thereby creating a temperature drop in the fluid by the magentocaloric effect. The heat of magnetization is converted into mechanical work by initially placing the fluid inside a sealed chamber with a door (76) that opens to a conduit leading into the bore of a superconducting solenoid (72). When the solenoid (72) is energized with current, it creates a strong axial magnetic field that exerts magnetic attractive forces on the fluid inside the chamber. When the fluid is released by opening the door (76), it is accelerated through the conduit (70) toward the superconducting solenoid where it becomes magnetized by the increasing strength of the magnetic field. By mounting a non-magnetic turbine (120) inside the conduit between the solenoid and the chamber, the kinetic energy of the accelerating flow stream, which is equal to the heat of magnetization, is converted into mechanical work thereby achieving isothermal magnetization. By removing the magnetic field after the fluid enters the bore of the solenoid, a temperature reduction is achieved thereby enabling the fluid to absorb heat in a cryogenic condenser.

A configuration of an NMR apparatus is provided. In the NMR apparatus, a magnetic field space of higher uniformity is generated by split superconducting magnets. At the same time, it is provided with a cryo probe excellent in cooling capability and sensitivity between two superconducting solenoid coils constructed in very close proximity to each other. For this purpose, a probe coil provided between the two superconducting solenoid coils is so constructed that the following is implemented: a certain distance is ensured between a substrate with a coil formed thereon and another, and the substrates and spacer substrates for cooling are alternately laminated. The spacer substrates are cooled by a cold head of sapphire. When the probe coil is inserted in the same direction as a sample tube (direction perpendicular to the static magnetic field), the spacer substrates cannot be coupled directly by the cold head of sapphire. Therefore, they are cooled through a fixed substrate for thermal conduction of sapphire coupled with the cold head.
