摘要：

Ab initio calculations reveal that Fe3Ru alloys of the D0(3), A15, and D0(22) structures will behave as ferromagnets. Moreover, Fe50Ru50 alloys of L2(a), B2, and alpha-NiAs structures will also behave ferromagnetically. In ion-beam-mixing experiments, a magnetic Fe50Ru50 alloy of B2, i.e., bcc, structure is obtained at a dose of 1x10(15) Xe+/cm(2). Interestingly, a nonmagnetic Fe50Ru50 alloy of L1(0), i.e., fcc, structure is also obtained under the same conditions and the predictions are in agreement with observations obtained from ion-beam-mixing experiments and magnetism measurements.
