Angular Variation of Coercivity in Orthoferrite Single Crystals

Abstract

The coercive force Hc as a function of the angle between the easy axis of magnetization and the external field has been studied in orthoferrite single crystals using the vibrating sample technique. The experimental results are in good agreement with the Kondorsky 180° wall motion model which predicts the relation Hc(0)/Hc(θ)=cosθ.
