چکیده

Dendritic flux penetration is a well known phenomenon in high temperature superconductors. We investigated the conditions under which this instability can be observed in different materials. We found three qualitatively different behaviors: dendrite development above a “critical field” and up to a certain temperature, above a “critical field” with no measurable temperature dependence, or no dendrite development at all.

By Korzhinsky and Schrienemakers, methods, phase relations of Mn-Al-Ca-silicates and other minerals in highly oxidized quartzites and schists of blueschist type metamorphism have been discussed. Because, such rocks were extensively studied in central Shikoku of Japan and in Andros and Evvia islands of Greece, they have been considered as thermodynamic system for discussion. The system contains ...

  A brief review on some peculiar properties of high temperature superconductors (HTS) is presented. Twenty years after the discovery, it appears more and more clear that the behaviour of this new class of materials is remarkably different from what have been re-classified as “conventional” superconductors. In the following we will focus our attention on the study of two phenomena, namely the J...
