Abstract
Articles according to the invention exemplarily comprise a magnetically hard oxide layer in contact with a magnetically soft oxide layer, with spins in the latter at room temperature exchange-coupled to the (oriented) spins in the former. Exemplarily both materials are ferrimagnetic spinel-type oxides, e.g., CoFe.sub.2 O.sub.4 /(Mn, Zn)Fe.sub.2 O.sub.4. Material combinations according to the invention can be advantageously used in high frequency circuit components such as inductors, since the magnetically soft layer can be in a substantially single domain state even after exposure to a magnetic field of considerable strength, e.g., up to about 500 Oe.
