Abstract

It was shown that in the Heisenberg frustrated antiferromagnetic Fe x Ni80−xCr20 alloys with the concentrations (x) near critical point the following succession of transitions is observed under cooling: paramagnet — collinear antiferromagnet- non-collinear antiferromagnet (antiasperomagnet) — reentrant spin glass. For the frustrated ferromagnetic (Fe x Mn1−x)Pt3 alloys the existence of slow relaxation processes was shown which are the result of dynamic crossover from the ferromagnetic state to an asperomagnetic one.
