Abstract
Ï-MnAl thin film was deposited by DC magnetron sputtering. Co thin film was deposited on the surface of Ï-MnAl thin film by Plasma Enhanced Atomic Layer Deposition (PEALD). In three parallel experiments, the Co layer thickness is controlled as 2, 4 and 6â¯nm, respectively. The surface chemical states of as-deposited Ï-MnAl and Co thin films were determined by XPS. The magnetic properties of both Ï-MnAl and Ï-MnAl/Co thin films were investigated by VSM. The results showed that when the Co layer thickness was 2 and 4â¯nm, effective magnetic exchange coupling was occurring between Ï-MnAl and Co, which was indicated by smooth magnetic hysteresis loops and enhanced (BH)max. However, when the Co layer thickness was increased to 6â¯nm, the magnetic exchange coupling between MnAl and Co was reduced, which was indicated by the kinks in the magnetic hysteresis loop and decreased (BH)max.
