Abstract
The effect of alloying with nonmagnetic Mg2+ ions on the low-frequency branch of resonance of a noncollinear quasi-one-dimensional CsNiBr3 antiferromagnet is investigated experimentally. It is found that a weak dilution (x=2 to 4%) leads to a considerable (up to 15%) reduction of the resonant gap and of the spin-flop field. The results agree with the theory of Korenblit and Schender, according to which the small parameter of perturbation of the initial system is \(x\sqrt {J/J'}\) rather than the impurity concentration x; i.e., a quasi-one-dimensional amplification coefficient exists, which is equal in this case to approximately six.
