Abstrakt

The structural and magnetic properties of polycrystalline Fe100-xMnx alloys with x = 38, 42, 46, 50, and 55 atomic percent were investigated after a heat treatment and a cold rolling process. According to X-ray diffraction (XRD), all samples crystallize into a gamma-phase. For cold rolled alloys x = 38 and 42, XRD analysis using pole figures showed no texture formation whereas cold rolled alloys with x = 46 and 50 exhibited texture components {110} <1-12 > and with x = 55, {011} <01-1 >. Magnetization measurements clearly demonstrate an antiferromagnetic type of ordering. For both the as-cast as well as the cold rolled materials, magnetostriction measurements at room temperature gave nearly zero magnetostriction.
