They are summed up here as follows: Method: Solid effect Substance used: La2 (0.01Nd) Mg3 (NOa)lE.24H20 crystal Polarization of H protons
A 3He-4He dilution refrigerator with a lowest temperature of 1.90 +\_\_ 0.05 mK and a maximum circulation rate of 10 mmol s -I has been constructed. The apparatus is at present used for the study of 3He in high magnetic fields and as a precooling stage for nuclear demagnetization. The design and con
