Hall effect at the magnetic-field-tuned superconductor-insulator transition
The Hall effect for disordered superconducting films in magnetic field is discussed, with special focus on the vicinity of the magnetic field-tuned superconductor-insulator transition. Evidence is presented that upon ensemble averaging this transition possesses a "hidden" particle/hole symmetry. This symmetry implies that right at the transition the Hall resistance vanishes. Relevance to recent...
متن کاملMagnetic field induced polarization effects in intrinsically granular superconductors
Based on the previously suggested model of nanoscale dislocations induced Josephson junctions and their arrays, we study the magnetic field induced electric polarization effects in intrinsically granular superconductors. In addition to a new phenomenon of chemomagnetoelectricity, the model predicts also a few other interesting effects, including charge analogues of Meissner paramagnetism (at lo...
متن کاملChange in Neutron Polarization Induced by a Superconductor Rotated in a Magnetic Field
Neutron depolarization iie. the change in the polarization vector projection onto the applied magnetic field) depends on neutron Larmor frequency UJL in the superconductor and
متن کاملLinear field demagnetization of artificial magnetic square ice
*Correspondence: Christopher H. Marrows, School of Physics and Astronomy, University of Leeds, Leeds LS2 9JT, UK e-mail: [email protected] We have studied experimentally the states formed in artificial square ice nanomagnet systems following demagnetization in a rotating in-plane applied magnetic field that reduces to zero in a manner that is linear in time. The final states are found to ...
متن کاملThe magnetic field induced phase separation in a model of a superconductor with local electron pairing.
We have studied the extended Hubbard model with pair hopping in the atomic limit for arbitrary electron density and chemical potential and focus on paramagnetic effects of the external magnetic field. The Hamiltonian considered consists of (i) the effective on-site interaction U and (ii) the intersite charge exchange interactions I, determining the hopping of electron pairs between nearest-neig...
