Abstract

A giant diamagnetism in the Co $_{2}$ CrAl compounds, in both bulk and thin film, below a certain temperature ( $T_z$ ) was observed. Above $T_z$ , 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.
