Abstract: | Induced anisotropy energy Ku and saturation magnetization M have been measured as a function of temperature T between 77 K and Tc on covenient specimens of amorphous Fe40Ni40P14B6 by means of a torque magnetometer. The M vs. T curve is found to follow an anomalously low behaviour with respect to crystalline materials. The expermental Ku vs. T curve is well fitted by a M2 law, also different from higher power laws typical of crystalline alloys. |
