Magnetic resonance analysis of spin dynamics in Sr2MnTiO5.87 double perovskite
The spin dynamics of the Sr 2 MnTiO 5 . 87 double perovskite have been studied via the magnetic resonance method. Two Lorenz lines below 100 K were used to describe magnetic resonance spectra. Using the Kawasaki-Mori-Huber and Vogel-Fulcher equations, the temperature dependence of the ESR line widths near the magnetic phase transition temperature have been described. The analysis of the line width in high-temperature limit allowed us to estimate the parameters of single-ion anisotropy and antisymmetric exchange interactions.
