Abstract
The structural and magnetostrictive properties of (CexTb1-x)(0.5)Pr0.5Fe2 w ere investigated. Ce-concentration must exceed x=0.6 in order to obtain the pure Laves phase. The magnetostriction and anisotropy constant increase wi th the Tb-content in this system. The anisotropy value of PrFe2 is lower th an that of isostructural DyFe2. From the X-ray step-scanned data we found t hat lambda(111) Of PrFe2 is 1310x10(-6). A large increase of magnetostricti on can be observed under a small prestress of 6 MPa for Ce0.5Pr0.5Fe2.
