Structure and magnetic properties in single crystal iron film
electrodeposited on a (110) copper crystal

Yuyi UEDA and Minoru Takahashi

Single crystal iron films with thickness of 100-1000A were
electrodeposited on the surface of copper single crystal substrate in
order to estimate how the characteristics of film differ from bulk
iron. The structure and the magnetism of the film in the thickness range
100-1000A were examined by electron diffraction and torque magnetometer.

Electron diffraction patterns of iron films prepared on the (110) plane of
a copper single crystal show the (211) plane of the iron body centered
cubic crystal. The <111> direction of the iron lattice is parallel to the
<110> of the copper substrate. A large uniaxial anisotropy was observed in
addition to the magnetocrystalline anisotropy in the iron single srystal
film. The origin of the anisotropy can be explained in terms of the
reverse effect of magnetostriction produced by an internal strain due to
the lattic misfit between the iron film and the copper substrate.
