Influence of chromium concentration on the electron magnetic resonance linewidth of Cr3+ in SrTiO3
Electron magnetic resonance (EMR) spectra of Cr3+ ions in samples of chromium-doped strontium titanate (SrTiO3) have been studied at room temperature for chromium concentrations between here 0.20 and 1.00 mol%.According to previous studies, chromium substitutes Ti4+ sites in the lattice and its preferred valence state is Cr4+, which is EMR silent i
