Soft magnetic materials with a Curie temperature (T{sub c}) close to room temperature are suitable candidates for device applications and for more fundamental aspects of magnetism. Promising candidates are Fe{sub 1−x}Cr{sub x}-alloys with a Fe concentration of about 25%–35%. We have grown by molecular beam epitaxy methods a number of epitaxial Fe{sub 1−x}Cr{sub x} alloys on MgO[100] and MgO[110] substrates, and we report on their structural and magnetic properties in this concentration range, including the dependence of the Curie temperature (T{sub c}) on the concentration, the magnetocrystalline anisotropy, and the development of the magnetic moment.
