【 摘 要 】
Detailed study of Ni75Al25 samples with varying degree of site disorder reveals that site disorder promotes magnetic excitations such as spin waves and local spin-density fluctuations and thereby reduces both spin-wave stiffness and Curie temperature. Irreversibility lines in the ð‘‡-ð» phase diagram of the weak itinerant ferromagnet Ni75Al25 have been determined for the ï¬rst time and the effect of site disorder on them has been ascertained.
