PURPOSE: To obtain a small-sized apparatus for measuring physical properties under magnetic field in which installation and running cost is reduced while facilitating replacement of sample. CONSTITUTION: In the apparatus for measuring physical properties under field wherein a sample holder 14 is disposed under the field generated from a superconducting magnet 13, the superconducting magnet 13 and the sample holder 14 are thermally coupled, respectively, with first and second stages 17, 18 of a two-stage refrigerator 16. Since only one refrigerator 16 is required, the size can be reduced along with the installation and running cost while facilitating the replacement of sample. Furthermore, the sample can be replaced quickly when the space for disposing the sample holder 14 is sealed hermetically with respect to the space for disposing the superconducting magnet 13 and a vacuum container 11 and the sample holder 14 can be opened directly to the outside of the vacuum container 11. |
