    The voltage–current characteristics of a superconducting coil, made of multifilamentary silver-sheathed Bi[sub 2]Sr[sub 2]Ca[sub 2]Cu[sub 3]O[sub 10+δ] tape, are investigated. We find that a small ac current I[sub ac] superimposed on a relatively large dc current I[sub dc] causes a...

    We describe an optical-lithography-based sample preparation technique for measuring the current-perpendicular-to-plane (CPP) magnetoresistance with micron-size current-contact areas on top of magnetic multilayer samples of millimeter in-plane size. We use Permalloy and Co[sub 91]Fe[sub 9]...

    In the present work, the effect of co-doping of Ta and Nb with nominal composition of (BiPb)TaSrCaCuNbO where x = 0.1 and y = 0.0, 0.025, 0.05, 0.075, and 0.1 were investigated. The samples were prepared by using the well-known conventional standard solid-state reaction method. The...

    We have measured ac magnetoresistance in fields up to 8 T in a variety of YBa2Cu3O7-δ single crystals containing (a) twin boundaries only in one direction, (b) multi-twin domain structure, and (c) growth steps. We find two components of the resistance: an angular dependent Lorentz force...

    Measurements of the magnetostriction of the isotropic high-temperature superconductor Ba[sub 0.66]K[sub 0.34]BiO[sub 3] revealed an effect of the order of 10[sup -6] which exceeds that for conventional superconductors but is not as high as the giant magnetostriction of cuprate high-temperature...

    The magnetoresistance (MR) ratio of spin valves can be improved by reducing the thickness of the nonmagnetic interlayer, such as Cu, due to not only reducing the shunt, but also increasing the probability of electrons scattered through the Cu. However, at small thickness, interlayer coupling...

    A study is made of the features of the magnetoresistance in ceramic Bi(Pb)-HTSCs containing trapped magnetic fields. It is found that upon trapping of magnetic flux in these granular HTSCs their magnetoresistance becomes anisotropic. For magnetic fields H parallel to the field H[SUBi] that has...
