Abstract
The paramagnetic - antiferromagnetic transition for an Fe - 31Mn - 3Al - 7Cr alloy was investigated by measurements of the susceptibility , the elastic modulus (E), the resistivity and the strain sensitivity coefficient of resistance (K). The results show that the alloy is a typical localized antiferromagnet. It has minima in the - T and E - T curves at the same temperature below the Néel temperature . The strain sensitivity coefficient of resistance (K) decreases drastically near and it tends to be stable when the temperature exceeds . A novel interpretation relating to the stress sensitivity coefficient of resistance (B) is proposed. The paramagnetic - antiferromagnetic transition has a much greater effect on B than it has on E; the temperature dependence of K is the same as that of B. It is suggested that the effect of stress on the energy band of the alloy may be the reason for the drastic change in K near and that the temperature dependence of K may be a new basis for understanding the energy gap in an antiferromagnetic alloy.
