Effect of order of stress and field application on changes in anhysteretic magnetization

Differences between isostress anhysteretics and the zero stress anhysteretic are found to be of the same form but larger than magnetization changes induced by stress from an anhysteretic point. The latter are separated into reversible and irreversible parts, indicating that pinning impedes changes from an anhysteretic point, thus giving smaller changes than the differences between the isostress anhysteretics
