Thulium iron garnet thin films substituted with bismuth and gallium were prepared by LPE from a PbO.B2O3 flux. Radioactive isotope tracers were added to the melt as the chemical analysis technique. The deviation from the ratio (Pb+Bi+Tm)/(Fe+Ga)=0.6

The complex polar Kerr effect (rotation and ellipticity) of CdCr2S4 has been measured between 1.6 and 4 eV at temperatures between Tc = 84 and 6 °K. Four well separated magneto-optical transitions have been identified. Two sharp peaks at 2.12 and 2.

The shapes of the proton magnetic resonance lines in a single crystal of CuSO4·5H2O have been measured between 20°K and 0.31°K, using a 3He cryostat for the temperature region below 1.2°K. Above about 3°K the line widths are roughly independent
