Abstract
A vibrating coil type magnetometer is described for measuring magnetization curves of small specimens in the magnetic cooling range of temperature. For a 3 mm diam sphere the sensitivity of magnetic moment measurements is 10−6 emu. At this sensitivity the amplitude of vibration is 0.5 mm, and at 0.3°K the extra heat influx into the sample thereby introduced is less than 10 erg/min. Examples of magnetization curves are shown.Keywords
