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 Handle Covers / Inserts room temperature for chromium concentrations between 0.20 and 1.00 mol%.According to previous studies, chromium substitutes Ti4+ sites in the lattice and its preferred valence state is Cr4+, wh

American cutaneous leishmaniasis (ACL) presents distinct active clinical forms with different grades of severity, known as localised (LCL), intermediate (ICL) and diffuse (DCL) cutaneous leishmaniasis.LCL and DCL are associated with a polarised T-helper (Th)1 and Outdoor Seating Th2 immune response, respectively, whereas ICL, or chronic cutaneous l
