Abstract
ESR and AFMR experiments have been performed at high frequencies and magnetic fields on the random antiferromagnetic mixture with competing spin anisotropies CsMn1-xCoxCl3.2H2O. The frequency vs. field plots of the resonance points are presented for several concentrations x and are analysed within the framework of usual antiferromagnetic theory.
