摘要：
An apparatus for magnetic susceptibility in the temperature range of 1.4-300 K is described. Measurements are performed in a portable helium or nitrogen Dewar flask. Magnetic susceptibility is measured by an ac mutual-inductance bridge (the frequency range is 17-6000 Hz). The sensitivity of the apparatus is 5.10(-8)-4.10(-7) cgsm units. Temperatures of 1.4-2.4 K are produced by a liquid-helium-filled Dewar insert, which ensures economical liquid-helium evacuation.
