Abstract
Description
Polycrystalline La2NiMnO6 compounds were fabricated at different temperatures and their magnetic properties were investigated. Although the antiferromagnetic antisite disorder degree changes a little, the antiferromagnetic coupling intensity increases with increasing synthesized temperature. When La2NiMnO6 sample was cooled at 100 Oe from room temperature to 10 K, exchange bias was observed. Our results confirm that the exchange bias should originate from the coupling between the ferromagnetic La2NiMnO6 and antiferromagnetic antiphase boundaries.
