Ny. Asadullina et al., EPR OF TRIVALENT CHROMIUM CENTERS WITH MONOCLINIC SYMMETRY IN SRF2 CRYSTALS, Physics of the solid state, 39(2), 1997, pp. 265-267
Cr3+ centers with monoclinic symmetry in SrF2:Cr crystals are studied
by EPR. Based on an analysis of the EPR data and a study of the condit
ions under which the observed samples were formed, a model is proposed
which explains the low symmetry of the magnetic properties in terms o
f the simultaneous effect on the impurity ion state of interactions wi
th the interstitial F- ion and with normal vibrations of the crystal l
attice in a trigonal symmetry. (C) 1997 American Institute of Physics.
