Abstract :
We measured tensor hysteresis loops for a 25.4 mm steel cube with compressive stress applied orthogonal to the field, and studied the repeatability of compressive stress effects in terms of the maximum magnetization and differential susceptibility amplitudes. The nonrepeatability of results and anomalous low stress behavior can be attributed to stress hysteresis, specifically to residual stress
