Properties of High-Tc Superconducting Magnetic Antenna for Alternating Vertical Magnetic Field

Heating magnetic fluid with alternating magnetic field

This study develops analytical relationships and computations of power dissipation in magnetic fluid (ferrofluid) subjected to alternating magnetic field. The dissipation results from the orientational relaxation of particles having thermal fluctuations in a viscous medium. r 2002 Elsevier Science B.V. All rights reserved.

Low-field magnetic resonance imaging with a high-Tc dc superconducting quantum interference device

A spectrometer incorporating a high transition temperature dc superconducting quantum interference device ~SQUID! is used to obtain nuclear magnetic resonance signals from protons in mineral oil at room temperature in fields up to 3 mT. The spatial separation between the SQUID magnetometer at 77 K and the sample at room temperature is less than 1 mm. At 2 mT, the signal is easily resolved in a ...

Superconducting properties of vacuum in strong magnetic field

Three-dimensional calculations of the magnetic fields in a finite superconducting hollow cylinder in an applied axial magnetic field

In this study, a set of self-consistent coupled-integral equations for the local magnetic flux and current distributions in a finite superconducting hollow cylinder under an axial magnetic field has been directly derived by using the Biot-Savart law within the framework of the critical-state model. The equations were first solved numerically in the three-dimensional space before obtaining the h...

Magnetic Field-Induced Landau Fermi Liquid in High-Tc Metals

We consider the behavior of strongly correlated electron liquid in hightemperature superconductors within the framework of the fermion condensation model. We show that at low temperatures the normal state recovered by the application of a magnetic field larger than the critical field can be viewed as Landau Fermi liquid induced by the magnetic field. In this state, the Wiedemann-Franz law is he...
