Structure and Magnetostriction of Pr_xTb_1-xFe_1.9Ti_0.1 Alloys

Abstract:

The structure and magnetostriction have been investigated for PrxTb1-xFe1.9Ti0.1 alloys by means of the X-ray diffraction phase analysis, vibrating sample magnetometer, and standard strain gauge technique. Comparing the structure of bulk and annealed samples, it can be found that the annealing treatment is of benefit to the formation of single phase with MgCu2-type crystal structure when x0.3. The magnetization at the maximal magnetic field decreases rapidly with increasing Pr content. The magnetostriction for Pr0.2Tb0.8Fe1.9Ti0.1 annealed sample at 900kA/m is 1733ppm. The magnetostriction for PrxTb1-xFe1.9Ti0.1 alloys at 900kA/m also decreases with increasing Pr content.
