Abstract:
Measurements of magnetization and 57Fe Mössbauer spectra have been made for Y(Fe1−xRux)2. The C15 type cubic structure is stabilized for x0.06 and the C14 type hexagonal structure for x 0.7. The C15 compounds is ferromagnetic with Tc200 K and its saturation moment decreases monotonically with increasing x, while the 57Fe hyperfine field decreases only slightly with x. From these results, it is deduced that the Ru atoms have an induced moment of ≈1μB in the range x 0.2. In the C14 type phase, no magnetic ordering develops even at 4.2 K.
