Abstract

We have grown (Mn_0.7Cr_0.3)₂As and (Fe_0.7Mn_0.3)₂As thin films directly on Si (1 0 0) substrate by molecular beam epitaxy at the substrate temperature, T_S=300 °C. We found that the crystal structure of (Mn_0.7Cr_0.3)₂As and (Fe_0.7Mn_0.3)₂ As thin films was the tetragonal Mn₂As type with the lattice constants of a=3.745 and 3.70Å, respectively. (Mn_0.7Cr_0.3)₂ As thin film shows spin-glass behaviour below 130 K, while (Fe_0.7Mn_0.3)₂As alloy has ferrimagnetic ordering at above room temperature.
