Abstract
Graded ceramics based on solid solutions of nickel-zinc ferrites (Ni1-хZnx)Fe2O4 (x = 0…0,2) was prepared by tape casting. The magnetic properties of the prepared samples were investigated. It is shown that the form and parameters of the experimental hysteresis loops consistent with the theoretically calculated. No hysteresis loop offset (along M- and B-axis) in the graded structures was observed. Tape casting method can be effective for manufacturing of compositionally graded magnetic materials (in particular, ferrites) with desired characteristics.
