Abstract

The magnetostriction, dynamic strain coefficient and magnetization processof a [111] oriented twin-free Tb0.27Dy0.73Fe2 single crystal along the [1 1 1], [1 1 2] and [1 1 0] directions were investigated by strain gauge, lock-in amplifier, double coiled induction and Bitter Colloid techniques. it is found that a 'jump' effect of magnetostriction along [1 1 (1) over bar] and [2 (1) over bar 1] directions occurs at a particular field and no 'jump'effect occurs in the direction of [0 1 1]. The value of the magnetostriction along [1 1 (1) over bar] direction is higher than that along [2 (1) overbar 1] direction and the 'jump' field for [1 1 (1) over bar] direction is much lower than that for [2 (1) over bar 1] direction. The magnetization process and dynamic strain coefficient, d(33), of the Tb0.27Dy0.73Fe2 single crystal along the [1 1 1], [1 1 2] and [1 1 0] directions were also discussed. The [1 1 1] oriented twin-free Tb0.27Dy0.73Fe2 single crystal possessesexcellent magnetostrictive properties along the rod direction ([1 1 1]) inlow magnetic fields and it is very useful in applications of industry.
