Abstract

This paper reports the experimental and theoretical study on the temperature dependence of the electron paramagnetic resonance (EPR) field at fixed frequency in a quadratic layer antiferromagnet k2MnF 4. The shift of EPR field (or EPR g-shift) from the value in the infinite temperature limit is theoretically shown to be a function of the parallel and perpendicular susceptibilities. The predictions of the theory are compared with the results of EPR and torque measurements performed on the single crystal of K2MnF4 at temperatures above the Néel point. Excellent agreement is obtained.
