Orientation Dependence of the Magnetic Moments of α-Fe(PrDy)(CoFeB) Microwires

The anisotropy of magnetization of microwires consisting of an α-Fe core and a (PrDy)(FeCo)B shell is studied at 300 K. The components of α-Fe core magnetization directed along the microwire axis and the noncollinear component of the microwire shell with different magnetization saturation fields of ~100 Ое and >10 kOe, respectively, are separated. The difference between the directions of magnetization of the shell and the core is 170°.
