Abstract

Co100−xMnx alloys form a system with competing magnetic interactions in the concentration range 25≤x≤42 at. %. They have ferromagnetic ground states in the fcc and hcp structures for 0≤x≤25 at. % and antiferromagnetic ground states in the fcc structure for 42≤x≤52 at. %. The thermal expansion of this alloy system has been measured between 4 and 1200 K and positive magnetovolume effects have been observed in samples that have both ferromagnetic and antiferromagnetic ground states.
