Research Abstract

The magnetization curve for two dimensional 3He on a triangular lattice was obtained at 1 mK, revealing a 1/2 plateau at 1.2-2.2 T and a shoulder at 2.5 T. To understand them the multiple spin exchange parameters are essential but it was found up to 6 bodies exchange parameters are not enough to explain the results. NMR signal from very dilute 3He atoms solved in solid 4He was successfully detected and it was found that 3He forms a small stable cluster. The growth mechanism of solid 4He in the porous aerogel was found due to a nucleation.
