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