Abstract

Textured Ni ₅₁Mn _28.5Ga _20.5 polycrystalline ribbons were prepared by melt spinning method with different spinning speeds. The effect of spinning speed on microstructure, phase transformation and magnetization behavior were investigated. The martensitic transformation temperatures were hardly affected by the spinning speed. The Curie temperature was significantly decreased, the saturation magnetization was reduced, and the critical field driving the detwinning was increased at higher spinning speed. Local and long-range effects were revealed for the melt spinning ribbons.
