Anisotropic spin-glass and magnetic behavior in single-crystalline U<inf>2</inf>PtSi<inf>3</inf>

2016, Journal of Alloys and CompoundsCitation Excerpt :Amidst materials with the composition U2TSi3, those with T = Co, Ni, Pd, Ir, Pt, Au adopt the AlB2-type unit cell. All of them exhibit behaviour typical for spin-glasses [1–11], e.g. frequency-dependent dynamic magnetic susceptibility, time-dependent magnetization decay, low-temperature minima in electrical resistivity followed by distinct upturns. In contrast, the compounds with T = Fe, Ru, Os crystallize with fully ordered unit cells, do not order magnetically down to lowest temperatures, and their physical characteristics are reminiscent of U-based intermetallic paramagnets [12,13].
Magnetic properties of metastable GdCr alloys
2011, Journal of Magnetism and Magnetic MaterialsCitation Excerpt :Since the hysteresis loops were obtained at a temperature of 2 K, which is well below the freezing temperature of all samples, another contribution to the coercive field may arise from an effective anisotropy field [36] due to the random freezing of the Gd clusters. Examination of the hysteresis loops for all alloys of this work reveal that the intercepts of these curves with the H axis are symmetrical with respect to the vertical axis, i.e., there is no exchange bias [37] (shift of hysteresis loops along the H axis). This implies that mechanisms leading to exchange anisotropy [30,38] are not operative even in the alloys of higher Gd concentration, despite the fact that antiferromagnetic (Cr) and ferromagnetic (Gd) phases are present in these alloys and antiferro–ferromagnetic interfaces necessarily exist.
