Angle-dependence of the Hall effect in Hg-Ba-Ca-Cu-O thin films
Abstract
Superconducting compounds of the family Hg-Ba-Ca-Cu-O have evoked intensive research efforts since the current record-holder for the highest critical temperature of a superconductor belongs to this class of materials. Thin films of the compound with two adjacent copper-oxide layers and a critical temperature of about 120 K were prepared by pulsed-laser deposition of precursor films and subsequent annealing in mercury-vapour atmosphere. Like other high-temperature superconductors, Hg-Ba-Ca-Cu-O exhibits a specific anomaly of the Hall effect, a double-sign change of the Hall coefficient close to the superconducting transition. We have investigated this phenomenon by measurements of the Hall effect at different angles between the magnetic field direction and the crystallographic c-axis. The results concerning the upper part of the transition, where the first sign change occurs, are discussed in terms of the renormalized fluctuation model for the Hall conductivity, adapted through the field rescaling procedure in order to take into account the arbitrary orientation of the magnetic field.
