Miniature cryostat for measurements on ferromagnetics between 1.6 and 300  K

The cryostat requires external supplies of the liquids helium, hydrogen and nitrogen. It operates within a working width of 19 mm at the specimen position, and the vertical height from specimen to top is 20 cm. It is used with the Sucksmith ring balance. Very steady specimen temperatures are possible throughout the range 1.6 to 300° K, and it is economical to operate.
