EFFECT OF ANTISYMMETRIC EXCHANGE INTERACTION ON THE MAGNETIZATION AND RESONANCE IN ANTIFERROMAGNETS.
Abstract
The magnetization curves and the resonance frequencies are calculated for two types of antiferromagnets with an antisymmetric exchange interaction of the forms D(ij).M(i) x M(j) and a uniaxial magnetocrystalline anisotropy interaction of the form K sin(squared)theta. In one type of antiferromagnet, the D vector is perpendicular to the easy axis. For this case, we have calculated the resonance frequency as a function of an external field applied parallel to the easy axis. In the second type of antiferromagnet the D vector lies parallel to the easy axis. For this case, we have calculated the resonance frequency as a function of an external field applied in the plane perpendicular to the easy axis. In both cases we obtained two resonance modes, and the lower mode was found to be W-=0 for a characteristic critical field. (Author)
