This work demonstrated two different kinds of magneto-transport behaviors in epitaxial L10 MnAl film as a function of temperature. The magneto-resistance ratio (MR) was negative and exhibited evident enhancement in the resistivity at coercive fields above 175K. The MR enhancement was attributed to the increase in the magnetic domain walls based on the quantitative correlation between the domain density and the resistivity. Below 175K, the MR was positive and showed a quadratic dependence on the external magnetic field, which implied that the MR was dominated by Lorentz effects. [ABSTRACT FROM AUTHOR] |
