We report on the structural, magnetic, and Raman-scattering studies of double-perovskite structure Sr 2 YRu 1−x Cu x O 6−␦ systems made by systematic synthesis processes with various numbers of doping concentrations and sintering temperatures. We observed different behaviors resulting from the different thermal treatments. In particular, superconductivity in Cu-doped Sr 2 YRuO 6 has been observed only for partially melted ceramic materials. We show that superconductivity is associated with the 1:2:3 phase ͑YSr 2 Cu 3 O t ͒, similar to that of Y-Sr-Cu-O samples sintered at high temperature.

“…It is well known that β-phase Ta has one of the largest spin Hall angles and the strongest spin-orbit coupling among all the possible Ta phases. Figure 4(b) shows the angular dependence of the ADMR amplitudes in the presence of an external magnetic field µ 0 H = 8 T. Note that Ta has been shown not to exhibit a significant anisotropic magnetoresistance arising from the magnetic proximity effect in YIG/Ta bilayers above 10 K [38]. In the same way, it is reported that the influence of magnetic proximity effect can be excluded in Cr 2 O 3 /Ta bilayers [39].…”

We report a combined study of imaging the antiferromagnetic (AFM) spin structure and measuring the spin Hall magnetoresistance (SMR) in epitaxial thin films of the insulating non-collinear antiferromagnet SmFeO 3 . Xray magnetic linear dichroism photoemission electron microscopy measurements reveal that the AFM spins of the SmFeO 3 (110) align in the plane of the film. Angularly dependent magnetoresistance measurements show that SmFeO 3 /Ta bilayers exhibit a positive SMR, in contrast to the negative SMR expected in previously studied collinear AFMs. The SMR amplitude increases linearly with increasing external magnetic field at higher magnetic field, suggesting that fieldinduced canting of the AFM spins plays an important role. In contrast, around the coercive field, no detectable SMR signal is observed, indicating that SMR of AFM and canting magnetization components cancel out. Below 50 K, the SMR amplitude increases sizably by a factor of two as compared to room temperature, which likely correlates with the long-range ordering of the Sm ions. Our results show that the SMR is a sensitive technique for non-equilibrium spin system of non-collinear AFM systems.

“…The electron dephasing time τ φ is a very important quantity that governs the mesoscopic phenomena at low temperatures. Particularly, the behavior of the dephasing time near zero temperature, τ 0 φ = τ φ (T → 0), has recently attracted vigorous experimental [1][2][3][4][5][6][7] and theoretical [8][9][10][11][12][13] attention. One of the central themes of this renewed interest is concerned with whether τ 0 φ should reach a finite or an infinite value as T → 0.…”

Effect of annealing on electron dephasing in three-dimensional polycrystalline metals

We have studied the effect of thermal annealing on electron dephasing times τ φ in three-dimensional polycrystalline metals. Measurements are performed on as-sputtered and annealed AuPd and Sb thick films, using weak-localization method. In all samples, we find that τ φ possesses an extremely weak temperature dependence as T → 0. Our results show that the effect of annealing is non-universal, and it depends strongly on the amount of disorder quenched in the microstructures during deposition. The observed "saturation" behavior of τ φ cannot be easily explained by magnetic scattering. We suggest that the issue of saturation can be better addressed in three-dimensional, rather than lowerdimensional, structures.
