Abstract
We report experimental and theoretical studies of the antiferromagnetic resonance in the compound (NH3)2(CH2)3MnCl4 which enable us to determine uniquely the magnitude of the effective fields of the exchange and relativistic interactions and to establish the magnetic structure of the material. It is shown that the structure of (NH3)2(CH2)3MnCl4 is significantly noncollinear.
