Magnetic and Mössbauer measurements were performed for Mn2–xFexP0.5As0.5, 0.5 =< x =< 1.0. It was shown that with decreasing Fe content magnetic interaction significantly weakens. Low temperature magnetic structure could be explained as a superposition of ferromagnetic and antiferromagnetic contributions to the whole magnetic moment of the alloy.
