A region of resistive domains is found in composite superconductors with thermal and electrical contact resistance between the normal metal matrix and the superconductor. The V-I characteristic of 3 sample with resistive domains is found. It is shown that the existence of resistive domains leads to the emergence of hysteresis upon decay and recovery of superconductivity in the presence of trans...

The minimum energy of a local heat pulse Qo, initiating normal zone propagation is an important characteristic of the stability of a superconducting composite. There are many papers concerning, both experimentally and theoretically (usually numerically), the value of Qc for composite superconductors (see, e.g., References 1-3 and references therein). In particular, simple analytical formulae fo...

Abstract Generation and detection of spinful Cooper pairs in conventional superconductors has been intensely pursued by designing increasingly complex magnet-superconductor hybrids. Here, we demonstrate theoretically that magnons with nonzero wavenumbers universally induce a cloud triplet around them an adjacent superconductor. The resulting composite quasiparticle, termed magnon-cooparon, cons...

In a composite superconductor in uniform rotation, the London field strength at equilibrium is given by the usual expression BL = 2mω/e; here m corresponds to the bare electron mass, although the effective mass m can be different in different layers. In the presence of strong angular accelerations, however, transient phases and differences in m can become relevant. In particular, if the layers ...

We find a type of normal domain in composite superconductors—a traveling rectangular domain. Using the effective circuit model we study in detail the dynamics of this domain. We derive an analytical solution for the propagation velocity and the length of a traveling rectangular domain. Current–voltage characteristics are calculated for a superconductor with a rectangular domain. © 1998 American...

Using the field-theoretical methods we studied the evolution from BCS description of a non-Fermi superconductor to that of Bose-Einstein condensation (BEC) in one loop approximation. We showed that the repulsive interaction between composite bosons is determined by the exponent α of the Anderson propagator in a two dimensional model. For α 6= 0 the crossover is also continous and for α = 0 we o...

We examine a contact between a superconductor whose order parameter changes sign across the Brillioun zone, and an ordinary, uniform-sign superconductor. Within a Ginzburg-Landau-type model, we find that if the barrier between the two superconductors is not too high, the frustration of the Josephson coupling between different portions of the Fermi surface across the contact can lead to surprisi...
