Magnetic Field induced Dimensional Crossover Phenomena in Cuprate Superconductors and their Implications
We discuss the occurrence of crossing points in the magnetization temperature (m,T ) plane within the framework of critical phenomena. It is shown that in a two-dimensional superconducting slab of thickness ds mz (δ) versus temperature T curves measured in different fields H = H (0, sin (δ) , cos (δ)) will cross at the critical temperature Tc of the slab. In contrast, in a 3D anisotropic bulk s...
متن کاملMagnetic Penetration Depth Measurements in Cuprate Superconductors
We examine recent results on measurements of the magnetic penetration depth in cuprate superconductors, with particular emphasis on our results obtained with the microstrip and parallel-plate resonator techniques. The results show that the magnetic penetration depth temperature dependence in YBa2Cu307-a is not consistent with a simple scaled weak-coupled BCS temperature dependence. We present t...
متن کاملDisorder-induced static antiferromagnetism in cuprate superconductors.
Using model calculations of a disordered d-wave superconductor with on-site Hubbard repulsion, we show how dopant disorder can stabilize novel states with antiferromagnetic order. We find that the critical strength of correlations or impurity potential necessary to create an ordered magnetic state in the presence of finite disorder is reduced compared to that required to create a single isolate...
متن کاملMagnetic field induced 3D to 1D crossover in type II superconductors
We review and analyze magnetization and specific heat investigations on type-II superconductors which uncover remarkable evidence for the magnetic field induced finite size effect and the associated 3D to 1D crossover which enhances thermal fluctuations. Indeed, the correlation length transverse to the magnetic field Hi, applied along the i-axis, cannot grow beyond the limiting magnetic length ...
متن کاملCompeting orders in a magnetic field: spin and charge order in the cuprate superconductors
We describe two-dimensional quantum spin fluctuations in a superconducting Abrikosov flux lattice induced by a magnetic field applied to a doped Mott insulator. Complete numerical solutions of a self-consistent large N theory provide detailed information on the phase diagram and on the spatial structure of the dynamic spin spectrum. Our results apply to phases with and without longrange spin de...
