Using magnetization, magneto-transport and single-crystal specific heat measurements we have determined the superconducting phase diagram of MgB 2 . The superconducting anisotropy γ changes monotonously from a value of around 2 near T c to above 4.5

We report on magnetoresistance measurements of the effects of 9 MeV proton irradiation on a clean, untwinned single crystal of ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$. For the first time, evidence for a

The critical points in untwinned YBa(2)Cu(3)O(7-delta) crystals with dilute columnar defects are investigated. We find a convergence of a first order vortex melting line with an irreversibility line associated with the onset of the Bose glass critica

The disordered vortex phases induced by line and point pinning in YBa2Cu3O7−δ are explored. At high defect densities, only a single disordered solid separated from the liquid phase by a melting line is observed. At low defect densities the topolog

Dynamic instabilities in the vortex lattice of YBa2Cu3O7−δ
Autor: W. K. Kwok, L. M. Paulius, J. A. Fendrich, G. W. Crabtree
Publikováno v: Physica C: Superconductivity. 293:111-117
A dynamic instability in the AC response of the vortex solid phase just below the melting/freezing line is reported. The instability takes the form of a voltage oscillation whose frequency is much lower than the driving frequency. The dependence of t

The superconducting phase diagram of ${\mathrm{MgB}}_{2}$ was determined from magnetization, magnetotransport, and single-crystal specific-heat measurements. A zero-temperature in-plane coherence length of 9.4 nm is determined. The superconducting an

We have measured the specific heat, resistivity, and ac susceptibility of K; Ba BiO3 single crystals before and after introduction of either point or columnar defects by electron (EI) or heavy-ion irradiation (HII).While the magnetic field dependence
