Abstract

The invention relates to non-Joulian magnetostriction (NJM) materials comprising transition metals, such as iron alloy magnets with non-Joulian magnetostriction (NJM). The invention also relates to reversibly linear non-dissipative transition metals magnets. The materials are capable of simultaneously large actuation in longitudinal and transverse directions, without simultaneous heat loss. The invention relates as well to methods of making non-Joulian magnetostriction (NJM) materials.
