Description
Summary:X-band (9.6 GHz) EPR studies on a single crystal of the solid-state-laser material Mn 5+-doped Ca 2PO 4Cl are reported at 295, 190, and 120 K. The Mn 5+ ion substitutes for the tetrahedrally coordinated P 5+ ion. The Mn 5+ fine- and hyperfine-structure spin-Hamiltonian parameters are evaluated rigorously from a simultaneous fitting of the EPR line positions observed for several orientations of the external magnetic field in the various magnetic planes. Enhanced thermal vibrations of MnO 3− 4 tetrahedra with increasing temperature are indicated from the temperature behavior of the width of EPR lines.
