At T = TSC, the identified critical exponents are 尾 = 2/3, 3/4 and 1. The large BC1 and BC2 values indicate that the two Cooper-pair electrons of the type II superconductors are much stronger coupled compared to the type I superconductors, remarkably, without a ...
We demonstrate the existence of a novel superconducting state in high quality two-component MgB2 single crystalline superconductors where a unique combination of both type-1 (kappa_1 < 0.707) and type-2 (kappa_2 > 0.707) superconductor conditions is realized for the two components of the order...

1 Type-I and type-II Dirac/Weyl points. A type-I Dirac point (4- band degeneracy point), characterized by a topological number NDP = ±1, consists of two type-I Weyl points (2-band degeneracy points) with opposite Chern number, C = ±1. A type-II Dirac point consists of two ...

CHAPTER 13–CRITICAL CURRENTS OF TYPE-II SUPERCONDUCTORSdoi:10.1016/B978-0-08-021651-5.50020-6A. Rose‐InnesIntroduction to Superconductivity
A simple vibrating coil magnetometer has been developed for use at temperatures above 1.5 K with a sensitivity of 104emu, permitting quantitative tests to be made of some recent developments in the theory of type II superconductors.关键词: n* --instrumentation--miscellaneous instruments & components...
Modeling of Magnetization and Intrinsic Properties of Ideal Type-II Superconductors in an External Magnetic Field O. Chevtchenko[1], J. Smit[1], D. de Vries[2], F. de Pont[2] [1]Delft University of Technology, Delft, Netherlands
The operational principle is based on quantum levitation of type-II high-temperature superconductors (HTSC) in the magnetic field. At the current stage, conceptual development of "EM-AC + PMG" hybrid accelerator is complete, and proof-of-principle experiments in mutually normal magnetic fields are...
Experimental evidence for flux-line cutting in superconductors (intersection and cross-joining of singly quantized vortices) is briefly reviewed. The interaction energy between two straight vortices tilted at an angle α (≠ 0)is then shown to be finite in the London model, i.e., in the limit...
