    Abstract: Some mechanical, electrical, and thermal properties of high Tc superconductors such as (Ba, Y) cuprates can be substantially improved by the dispersal of an appropriate metal in the superconductive body. For instance, mixing Ag particles with superconductive powder of nominal composition Ba2YCu3O7 and processing the mixture in the conventional manner can produce superconductive bodies having Tc of about 93 K and substantially greater fracture strength and normal state electrical and thermal conductivity than otherwise identical bodies that do not contain Ag particles.

    Abstract: The device has a single strip having a first end, a second end, a length and a width. The first end of the strip is curved toward the second end of the strip to form a loop having a height. The length is approximately 10 mm, the width is approximately 5-8 mm, and the height is approximately 0.8-1.2 mm. The loop is preferably fabricated from copper. The loop is mounted directly to a test instrument such as a computer controlled impedance analyzer or network analyzer. The test instrument measures the inductance and resistance of the loop with no thin film sample placed therein, and then measures the inductance and resistance of the loop containing the sample under test. From these measurements, the device ultimately derives the permeability of the sample under test. The method for measuring the complex permeability of thin films at ultra-high frequencies includes the steps of recording the residual inductance and resistance for the loop empty; measuring the total inductance and resistance for the loop loaded with the sample under test; determining the change in resistance by subtracting the resistance of the loop without any sample from the resistance when the loop is loaded with the sample under test; determining the change in inductance by subtracting the inductance of the loop without any sample from the inductance when the loop is loaded with the sample under test; and calculating permeability.

    Abstract: The present invention is a planar spiral inductor a top magnetic layer a bottom magnetic layer; and a plurality of conductive coils disposed between said top magnetic layer and said bottom magnetic layer. A significant difference from prior art is that the top and bottom magnetic layers have their centers effectively cut out using lithographic techniques or other techniques to frame the core of the conductive spirals. An advantage of this structure over the prior art is that when magnetic anisotropies other than shape are kept small, then the magnetic configuration will produce a magnetostatic shape anisotropy such that the easy axis (low energy direction of magnetization) lies parallel to the legs of a rectangular frame or the circumference of a circular frame, as will be described. During operation of the inductor, the field produced by the coils flows in a radial direction and will be perpendicular to the easy axis direction thereby causing magnetization reversal to occur by rotation while advantageously utilizing the full structure in this mode.
