Structure sensitive magnetic properties of Ni-Mn alloys.

Quenched Ni-Mn alloys exhibit both a spin-glass state and ferromagnetism for Mn concentrations (C(Mn)) below 26 at %. While previous studies concentrated on understanding various aspects of the magnetic properties (hysteresis, field cooling effects, anisotropy, spin waves, etc.), the present study focuses on the effect of structure by sputtering Ni-Mn alloys at temperatures (T (D)) ranging from 77K to 1173K.
