摘要：

This paper reports an EPR study of the effect of hydrostatic pressure (up to 10 kbar) and temperature (300, 77, and 4.2 K) on the spin Hamiltonian parameters of the Eu2+ ion in a SrCl2 cubic crystal. It is found that the b(4) parameter is related by a power law to the distance from the Cl-1 ligand (b(4) similar to R-13.5). The pressure and temperature are shown not to be equivalent thermodynamic parameters. Lattice vibrations contribute noticeably to the initial S-ion splitting. (C) 2001 MAIK "Nauka/Interperiodica".
