Structure and magnetism in DyxPr1-x and ErxPr1-x alloys: I. Hexagonal close-packed and Sm structures

Abstract:

Epitaxial thin films of dysprosium-praseodymium and erbium-praseodymium alloys have been studied using neutron and x-ray diffraction. The magnetic and structural properties have been determined for DyxPr1-x for 1.0 ≥ x ≥ 0.5 and for Er0.5Pr0.5. The crystal structure is hexagonal close-packed (hcp) for 1.0 ≥ x ≥ 0.6 and changes to the Sm type for x ∼ 0.5. The hcp samples form basal-plane helices with a transition to ferromagnetism accompanied by a discontinuity in the lattice parameter c. The ...
