A calorimetric study of the effects of surface energy in a type II superconductor
… on ellipsoidal samples of first and second kind superconductors. The measurements were performed using a specially designed magnetization calorimeter by two different techniques. The measurements were made on lead, tin, lead-4at%thallium, and tin-6at% indium. The results confirm the existence and …

Correlation lengths, disorder, and dynamics of vortex matter as heard through the noise
… measuring flux-flow voltage noise in the type II superconductor 2H-NbSe₂ concentrating on the dynamics and possible phase transitions of vortex matter associated with the peak-effect. I emphasize five conclusions: (1) Traditional models of vortex dynamics relying on purely dynamical …

The Effects of Annealing URu2Si2 on the Resistivity and Meissner Effect
… Sample1-1 shows a typical field dependence of a Type-II superconductor. The lower critical field Hc1 is relatively high, which may be due to flux pinning by the crystal defects.

The Bogoliubov equations and their application to a normal-superconducting boundary
… a norma1- superconducting boundary in an extreme type I superconductor, The method of the Bogoliubov equations has three advantages, for this calculation, over other methods: (1) the method offers a practical means of investigating the properties of a norma1- superconducting boundary for all …

Advanced Numerical Modelling of Bulk Superconductor Magnetisation
… volume, below a certain (critical) temperature. Superconductors can be subdivided into two classifications; type-I, or type-II, with the latter exhibiting a ‘mixed-state’ of superconductivity across their volume. Through appropriate magnetisation, magnetic flux may become ‘pinned’ within type-II …

An investigation into high temperature superconducting flux pump technology with the circular type magnetic flux pump devices and YBaCuO films
… wave on HTS films such as YBa2Cu3O7-δ, two types of circular-type magnetic flux pump (CTMFP) devices were proposed and built. These novel devices generate an annular-shape travelling magnetic wave. The first type was the original CTMFP magnet, which produces the longest wavelength of …
