摘要： Articles according to the invention exemplarily comprise a magnetically hard oxide layer (e.g., 81) in contact with a magnetically soft oxide layer (e.g., 82), 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 2 O 4 /(Mn, Zn)Fe 2 O 4 . Material combinations according to the invention can be advantageously used in high frequency circuit components such as inductors (e.g., 70), 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.
