The authors present a review of recent muon spin rotation (μSR) studies of the vortex state in
type-II superconductors. There are significant gaps in our understanding of this unusual …

A systematic study is made of the tJ model as a working model for copper oxide high-T c
superconductors. The main focus is on the near-half-filling region (low hole concentrations) …

This book presents the anisotropy and multiband effects in newly discovered unconventional
superconductors: cuprate superconductors, borocarbides, magnezium-diboride and …

Based on a two-dimensional odd-parity superconducting order parameter for Sr 2 RuO 4
with p-wave symmetry, we investigate the single vortex and vortex lattice structure of the …

It is argued that the dx2–y2 superconductor exhibits a transition into the dx2–y2+ idxy state
in the presence of magnetic impurities in certain conditions. Linear coupling between …

В течение уже тридцати с лишним лет основной моделью в теории металлических
магнетиков является модель Хаббарда [1]. Она была предложена первоначально для …

We study the effect of the superconducting gap nodes on the vortex lattice properties of high-
temperature superconductors at very low temperatures. The nonlinear, nonlocal, and …

The notion that electrons in high-T c cuprates pair via antiferromagnetic spin fluctuations is
discussed and the symmetry of the superconducting order parameter is analyzed. Three …

We consider a superconducting state with mixed-symmetry order parameter components,
eg, d+ is or d+ id′ with d′= d xy. We argue for the existence of a new orbital magnetization …

In this paper, we study a recently proposed Ginzburg--Landau-type model for some high-Tc
superconductors with d-wave pairing symmetry. The scalar complex order parameter used …
