Abstract
We have prepared (100) oriented iron-iridium superlattices by MBE. For thin iron layers we obtain a bct phase (body-centered tetragonal) wit h a c/a ratio equal to 1.25, corresponding to a strained fcc Fe struct ure. This phase is found to be nonmagnetic at room temperature. Howeve r, thermomagnetic measurements evidence a transition to ferromagnetic order at low temperature.
