โฆ Synopsis
A description of the apparatus used for obtaining very low temperatures by the method of adiabatic demagnetisation is given. The method is discussed. Measurements have been carried out on Cerous fluoride, Dysprosium ethylsulfate and Cerium-ethylsulfate. The latter salt gave the lowest temperature of 0.085 ยฐK, Difficulties in fixing the temperature scale are discussed. l "-~!.~ ~J~r -~ 3---v-~--t ~H~iII~IVHIt "V "tt (IhIV VIAISH~IIA~.
