摘要：

The temperature dependence of the unusual magnetic 90-degrees coupling in epitaxial Fe/Al/Fe(001) trilayers has been determined. Trilayers with Al thickness near 15 angstrom exhibit a rapid decrease of coupling strength (B-12) with increasing temperature. This temperature dependence is well described by the relations B-12 = B-12(0)(1 - T/T0)2 or B-12 = B-12(0) exp(-T/T0) which contrast with the approximately linear temperature dependence previously reported for 180-degrees coupled systems.
