| Zusammenfassung | By 3 neutron depolarization (ND) the magnetization and the domain structure were observed for FC and ZFC samples of (PD 0.9965Fe0.0035)1-x Mnx with x = 0.05, showing both an FM and a spin-glass-like transition, and x = 0 being ferromagnetic. The evolution of the domain structure along the magnetization/demagnetization process - as seen by depolarization - is strongly asymmetric, with maximum change in the domain structure only after magnetization reversal (typical domain size δ ≈ 3μm in the virgin state). Near Tc, the alloy approached the behavior of FM PdFe, showing a symmetric change of domain structure on the applied field. |
