Giant diamagnetism in half-metallic CoCrAl Heusler alloy
arXiv:0906.0824
Abstract
A giant diamagnetism in the CoCrAl compounds, in both bulk and thin film, below a certain temperature () was observed. Above , the compound behaves as an ordinary ferromagnet. The diamagnetic alignment might be initiated by the Landau diamagnetism because of the half-metallic properties and the pinning of the diamagnetism is preserved by the peculiar electronic structures.
