Abstract
Recently, two of us have developed the technology for preparing homogeneous thin films of the spinel CdCr 2 Se 4 with varying amounts of In impurity. Ferromagnetic resonance (FMR) and spin wave resonance (SWR) measurements at 10 GHz at temperatures (T) varying between 4 and 300 K were used to elucidate the magnetic state -- ferromagnet (FM) re-entrant (REE) or spin glass (SG), of the material as a function of In content. However, it is realized that a thorough understanding is not possible without making resonance measurements at several frequencies. For instance, it is impossible to delineate various contributions to the peak-to-peak linewidth (Γ PP ) without knowing its frequency dependence. The present report is based on magnetic resonance data on thin films of CdCr 2-x In x Se 4 at several frequencies between 3 and 36 GHz and at 77 < T < 200 K. We will also report on the remarkable sensitivity of the resonance parameters to exposure, of the sample, to modest (-1 mW) amounts of light from a tungsten lamp over a period of a few seconds.
