Abstract :
Electron spin resonance measurements on CdCr2-xInx Se4 thin films are reported. For x<0.01, data spanning wide ranges of frequency and temperature show that the material is a reentrant magnetic system. The x=0.4 compound is a spin glass, and its field induced magnetization at 77 K is affected markedly by exposure to a few milliwatts of 0.9-μm radiation
