Strain-field relationships in rare-earth iron alloys

We have measured large scale strain as a function of field and external stress in two rare-earth iron alloys. From this data we calculate the external work and find it modified by various defects. The defects are characterized by a single parameter, T o . A large scale figure-of-merit is found that...

Description
Summary:We have measured large scale strain as a function of field and external stress in two rare-earth iron alloys. From this data we calculate the external work and find it modified by various defects. The defects are characterized by a single parameter, T o . A large scale figure-of-merit is found that exceeds that of hydraulics or electric motors.
