Abstract
A new method for the determination of anisotropy held strength in specimens with uniaxial anisotropy is described. Longitudinal MOKE is used in combin ation with a rotating magnetic field. Due to sufficient large field strengt h, a Stoner-Wohlfarth-like magnetisation reversal process can be realised. By correcting higher-order MOKE terms, a highly accurate calculation of H-k is demonstrated on different Fe, NiFe and Co ultra thin films. (C) 1999 El sevier Science B.V. All rights reserved.
