Anomalous transport through the p-wave superconducting channel in the 3-K phase of Sr2rRuO4.

چکیده
Using microfabrication techniques, we extracted individual channels of 3-kelvin (3-K) phase superconductivity in Sr2RuO4-Ru eutectic systems and confirmed odd-parity superconductivity in the 3-K phase, similar to pure Sr2RuO4. Unusual hysteresis in the differential resistance-current and voltage-current characteristics observed below 2 K indicates the internal degrees of freedom of the superconducting state. A possible origin of the hysteresis is current-induced chiral-domain-wall motion due to the chiral p-wave state.

Single phase polycrystalline Gd1-xPrxBa2Cu3O7-δ samples with x=0.05 , 0.10, and 0.15 have been prepared by standard solid state reaction technique and characterized by XRD and SEM analysis. The electrical resistivity, Hall effect and magnetoresistance measurements have been on the samples. The electrical resistivity measurements indicate a reduction of transition temperature (Tc) and an incre...
متن کاملSuperconducting transition of Ru in SQUIDs with Nb/Ru/Sr2RuO4 junctions
We have measured transport properties and magnetic responses of direct current superconducting quantum interference devices(dc-SQUIDs) with Nb/Ru/Sr2RuO4 junctions on the same Ru inclusion of a Sr2RuO4-Ru eutectic crystal. We observed a superconducting transition of the Ru at 0.50 K and another transition with anomalous interference patterns of the SQUID at 0.40 K. The second transition led to ...
متن کاملEffects of Slip and Heat Transfer on MHD Peristaltic Flow in An Inclined Asymmetric Channel
Peristaltic transport of an incompressible electrically conducting viscous fluid in an inclined planar asymmetric channel is studied. The asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitude and phase. The closed form solutions of momentum and energy equation in presence of viscous dissipation term are obtained for long wave length and low Reynol...
متن کاملPolaron coherence as origin of the pseudogap phase in high temperature superconducting cuprates
Within a two-component approach to high T c copper oxides including polaronic couplings, we identify the pseudogap phase as the onset of polaron ordering. This ordering persists in the superconducting phase. A huge isotope effect on the pseudogap onset temperature T * is predicted and in agreement with experimental data. The anomalous temperature dependence of the mean square copper-oxygen ion ...

In this paper, we analyze the thermal radiation and chemical reaction impacts on MHD peristaltic motion of the Eyring-Powell fluid through a porous medium in a channel with compliant walls under slip conditions for velocity, temperature, and concentration. Assumptions of a long wave length and low Reynolds number are considered. The modeled equations are computed by using the perturbation metho...
