A series of KNi x Mn 1− x F 3 (0.3 < x < 0.8) with cubic structure is examined by electron paramagnetic resonance in the region of the magnetic phase transition. The broadening of the linewidth Δ B and the shift of the resonance field B r at a fixed frequency are caused by the onset of magnetic ordering. This work proves Huber's theory that the effects observed near magnetic phase transitions in antiferromagnets depend on the symmetry of the system examined.
