Possible twin-boundary effect upon the properties of high-Tc superconductors.
نویسندگان
چکیده
We have studied the field at which superconductivity nucleates in grain-aligned samples of Y1Ba2Cu3O7-δ very close to the transition temperature Tc. For the field parallel to the c axis and for temperatures within 2 K of Tc, the nucleation field is found to vary as (1-T/Tc)1/2. The data suggest that superconductivity localized near twin boundaries may exist at temperatures close to Tc. .AE

Quasiclassical Theory of Twin Boundaries in High-Tc Superconductors
We investigate the electronic structure of twin boundaries in orthorhombically distorted high-Tc materials using the quasiclassical theory of superconductivity. At low temperatures we find a local instability to a time-reversal symmetry breaking state at the twin boundary. This state yields spontaneous currents along the twin boundary that are microscopically explained by the structure of the q...

In this paper, a dc Josephson junction between two singlet superconductors (d-wave and s-wave) with arbitrary reflection coefficient has been investigated theoretically. For the case of high Tc superconductors, the c-axes are parallel to an interface with finite transparency and their ab-planes have a mis-orientation. The physics of potential barrier will be demonstrated by a transparency coeff...
متن کاملThermal Mechanisms of Stable Macroscopic Penetration of Applied Currents in High Temperature Superconductors and their Instability Conditions
Macroscopic mechanisms of applied current penetration in high-Tc superconductors are discussed to understand the basic physical trends, which are characteristic for the stable and unstable formation of the thermo-electrodynamics states of high-Tc superconductors placed in DC external magnetic field. The performed analysis shows that the definition of the current stability conditions of high-Tc ...
متن کاملOxygen Disorder Effects in High Tc Superconductors
It is now well established that oxygen plays a crucial role in the structural, magnetic and transport properties of high Tc materials. We present here a brief review of the effect of the oxygen deficiency and vacancy ordering on the superconducting and magnetic properties of various superconductors.
متن کاملEffect of Transparency on the Josephson Junction between D-wave Superconductors
In this paper, a dc Josephson junction between two singlet superconductors (d-wave and s-wave) with arbitrary reflection coefficient has been investigated theoretically following the famous paper [ Y. Tanaka and S. Kashiwaya 1996 Phys. Rev. B 53, R11957]. For the case of High Tc superconductors, the c-axes are parallel to an interface with finite transparency and their ab-planes have a mis-orie...
