Abstract
The results of a study on the effects of neon implantation into bubble films are presented. Epitaxial films of composition La, Ga:YIG and Tm, Ca, Ge:YIG were implanted with 300 keV, 1014 Ne+ ions/cm2. The films were studied by ferromagnetic resonance (FMR) and by double crystal X‐ray diffraction. The FMR spectra of the ion‐implanted films exhibit an additional set of clearly observable spin wave resonances. Numerical calculations for the La, Ga:YIG film yield an anisotropy profile in the implanted layer, while moreover a decrease in the exchange constant was found. These findings were confirmed by an etching experiment. A good agreement between the maximum of the strain profile, as deduced from double crystal X‐ray measurements, and the estimated anisotropy profile was found.This publication has 7 references indexed in Scilit:
