FREQUENCY DEPENDENCE OF MN2+ ION ELECTRON SPIN RESONANCE SPECTRA IN THE ULTRA-HIGH-FREQUENCY BAND

摘要

Low-frequency measurements for extracting hyperfine structure (HFS) parameters directly from the experimental ESR spectra of glasses are described. Glass of molar composition BaO-P2O5 with 0.2 wt% Mn2O3 was used. The spectra were recorded at room temperature in the UHF band at various frequencies (of 530 to 950 MHz). The HFS parameter A(0) was determined using the frequency dependence of the spectra. [References: 13]
