Atomic vacancy defect in 〈110〉 oriented TbDyFe alloy and its effect on the magnetostrictions

The atomic vacancies of 110 oriented TbDyFe rods with different heat treatment have been investigated by the positron annihilation technique. It has been found that the concentration of atomic vacancy is the highest in the sample solidified directionally. However, the concentration of vacancy decrea...

Summary:The atomic vacancies of 110 oriented TbDyFe rods with different heat treatment have been investigated by the positron annihilation technique. It has been found that the concentration of atomic vacancy is the highest in the sample solidified directionally. However, the concentration of vacancy decreases sharply with increase of annealing temperature and reaches the minimum value of 154ps at 1293K. Magnetostriction measurement shows that reducing the concentration of vacancy is favorable to enhance magnetostrictive property of the alloy.
