Abstract
The temperature behavior of the EPR spectra of the Gd3+ impurity center in single crystals of SrMoO4 in the temperature range T = 99–375 K is studied. The analysis of the temperature dependences of the spin Hamiltonian b 02 (T) = b2(F) + b2(L) and P 02 (T) = P2(F) + P2(L) (for Gd157) describing the EPR spectrum and contributing to the Gd3+ ground state splitting ΔE is carried out. In terms of the Newman model, the values of b2(L) and P2(L) depending on the thermal expansion of the static lattice are estimated; the b2(F) and P2(F) spin-phonon contributions determined by the lattice ion oscillations are separated. The analysis of b 02 (T) and P 02 (T) is evidence of the positive contribution of the spin-phonon interaction; the model of the local oscillations of the impurity cluster with close frequencies ω describes well the temperature behavior of b2(F) and P2(F).
