Magnetic-Field-Driven Superconductor-Insulator-Type Transition in Graphite

A magnetic-field-driven transition from metallicto semiconducting-type behavior in the basal-plane resistance takes place in highly oriented pyrolytic graphite at a field Hc ∼ 1 kOe applied along the hexagonal c-axis. The analysis of the data reveals a striking similarity between this transition and that measured in thinfilm superconductors and Si MOSFET’s. However, in contrast to those materia...

A Holographic Superconductor in an External Magnetic Field

We study a system of a complex charged scalar coupled to a Reissner–Nordström black hole in 3+1 dimensional anti–de Sitter spacetime, neglecting back–reaction. With suitable boundary conditions, the cases of a neutral and purely electric black hole have been studied in various limits and were shown to yield key elements of superconductivity in the dual 2+1 dimensional field theory, forming a co...

On the Magnetic-Field Dependence of the Longitudinal Ultrasonic Attenuation in a Type-II Superconductor

We propose a simple method by which we can explain the magnetic-field dependence of the longitudinal ultrasonic attenuation in a type-II superconductor. It gives a curve which is in good agreement with experimental data, in paticular, near the lower critical field Hc1. We compare it with conventional methods, which is not in good agreement with the experimental data near Hc1 but near the upper ...

Designated magnetic field design for magnetic drug guidance in BNCT

In this paper, a local magnetic field was designed and simulated using a Helmholtz coil along with a ferromagnetic core with an appropriate geometric Structure to concentrate a magnetic flux. This field can be used for magnetic guiding of Boron-borne drugs in BNCT.

Search for a vortex loop blowout transition in a type-II superconductor in a finite magnetic field

The three-dimensional uniformly frustrated XY model is simulated to search for a predicted ‘‘vortex loop’’ transition within the vortex line liquid phase of a strongly type-II superconductor in an applied magnetic field. Results are shown to strongly depend on the precise scheme used to trace out vortex line paths. While we find evidence for a transverse vortex path percolation transition, no s...
