Magnetocrystallographic anisotropy in nickel-zinc and nickel-manganese ferrite single crystals

Temperature dependence of the first-order magnetocrystallographic anisotropy constant in nickel-zinc and nickel-manganese ferrite single crystals grown using the Verneuil method has been investigated. The anisotropy constant K₁ was measured by the torque in the temperature range 77° to 500°K. The results obtained are discussed on the basis of the one-ion (single-ionic) model taking into account the ionic distribution of two-valence metals on the sublattices.
