Nanocrystalline Soft Magnetic Fe-, Co-Based Alloys Doped by Hf, Mo and Zr with Enhanced Thermal Stability of Magnetic Properties

Abstract:

Magnetic properties, thermal stability and structure of the alloys - (Fe_0.6Co_0.4)₈₆Hf₇B₆Cu₁ (1), (Fe_0.7Co_0.3)₈₈Hf₇B₄Cu₁ (2) and (Fe_0.7Co_0.3)₈₈Hf₄Mo₂Zr₁B₄Cu₁ (3) obtained in the form of ribbons quenched from the melt were investigated after their nanocrystallization in the course of the thermal (TA) and stress (SA) annealings in the air at different temperatures. In all three alloys SA resulted in the induction of magnetic anisotropy with an easy axis along the direction of the ribbon. It is established that the alloy 3 after SA at 620°C for 20 min has the best thermal stability of magnetic properties, which remained practically unchanged after the subsequent annealing at 550°C for 26 hours. Magnetic properties of the alloys 1 and 2 subjected to SA under the same conditions did not change after annealing at 500°C.
