摘要：

We have studied the growth and magnetic properties of molecular beam epitaxy grown layers of bcc Fe(001) on MgO(001) substrates at a wide range of temperatures. For growth temperatures in the range 80-595 K, the iron forms islands which increase in lateral size with increasing temperature. Completed films in the same temperature range show the magnetic properties expected for a system with biaxial anisotropy, and a coercivity of < 10 Oe. The value of the first cubic anisotropy constant divided by the magnetization (K-1/M) remained constant. No evidence for uniaxial magnetic anisotropy in the films was found. Above 595 K, the films' structure and magnetic properties changed dramatically to those characteristic of a particulate system. (C) 1998 American Institute of Physics. [S0021-8979(98)06315-4].
