MAGNETOSTATIC MODES IN ANTIFERROMAGNETS AND CANTED ANTIFERROMAGNETS,

Abstract

The resonance frequencies of the magnetostatic modes are calculated for an antiferromagnetic sphere with a.d.c. magnetic field applied along the direction of easy magnetization. The magnetostatic modes of canted antiferromagnets of the alpha-Fe2O3 type are also investigated. Application of the magnetostatic conditions and solution of the differential equation for the magnetic scalar potential for a spherical sample reveals separations between modes of order 0.1(H(o)+H(DM) 4piM/H(ex)oe. These modes are associated with the low frequency resonance near omega (1). (Author)
