SQUID susceptibility measurements of the high Tc superconductor Sr0.2La1.8CuO4, with a 40 K resistive onset, are reported for fields from 1 μT to 4.5 T (10 mG to 45 kG). Data show an average lower critical field of 30 mT at 5 K, but with nonlinearit

Convenient and inclusive tables for the demagnetization factors of general ellipsoids are calculated by an APL program using the mathematical framework of Osborn [Phys. Rev. 67, 351 (1945)] along with elliptical integral function tables of Spenceley

Magnetization measurements on many single crystals of YBaCuO as well as BiSrCaCuO show a non-vanishing remanent magnetization in a region where the field-cooled and zero-field-cooled magnetizations coincide. We call this kind of remanence “residual

We discuss the zero‐field cooled (ZFC), field‐cooled (FC), and remanent (rem) magnetization of YBaCuO crystals in the context of an extended Bean critical‐state model. We introduce a novel way to include the reversible magnetization in this the

Patterned laser illumination incident upon superconducting films is shown to be capable of creating dynamic superconducting-normal ($S\ensuremath{-}N$) interfaces with almost any desired pattern. The width of such a dynamic interface for a sharp illu

Picosecond laser pulses are used, for the first time, to excite superconducting Pb films out of equilibrium. Pb microbridges are used to measure the threshold power needed to drive the Pb film normal as a function of temperature. Pb tunnel junctions

The I-V curves of rf-driven underdamped Josephson junctions have been studied in detail both experimentally and numerically. Very large negatively going tails on top of Shapiro steps in the intermediate-dc-current range and smaller wiggling distortio

Two sets of CaWO4:Nd:Na crystals have been grown having Nd concentrations of 0.5 and 1.0 at.%, and various concentrations of Na. The photolytic coloring is somewhat enhanced by the presence of Na, whereas reduction coloring is made much more difficul

Measurements of the photoconductivity of bicrystal dislocation planes are analysed. These measurements suggest the existence of a midband level at 0·42 eV from the valence band for these 20° tilt boundaries. The measurements of the photoresponse of
