Exchange Anisotropy of Ferrimagnetic Precipitates of Nickel Oxide in NiO Matrix

Kimihito Tagaya

(Received February 16, 1981)

When the spins of small ferrimagnetic precipitates of nickel oxide with a spinel-type defect structure are coupled with the spins of the antiferromagnetic NiO matrix by exchange interaction across the interface, an exchange anisotropy is produced in each ferrimagnetic precipitate. Ferromagnetic resonance and electron micrographical examinations were performed on such precipitates of nickel oxide. The exchange anisotropy of the precipitates was studied, and the value of exchange anisotropy energy per cm² of interface between ferrimagnetic nickel oxide and antiferromagnetic NiO was estimated. ©1981 The Physical Society of Japan
