✦ Synopsis

Magnetic phase diagrams of the Fe(Pda_xAux)3, (Fel_xMnx)Pd3, Fe(Pdl_xPtx) 3 and (Fe~_xMnx)Pt alloys with competing exchange interactions between magnetic atoms are discussed in terms of a phenomenological theory of phase transitions with related order parameters. The peculiarities of the ferro-antiferromagnetic transition are connected with the magnetoelastic interaction and with a change in sign of the exchange integral between magnetic atoms.
