High field study of normal state magneto-transport in the thallium cuprate Tl-2201

TL;DR

This study investigates the in-plane magneto-transport properties of Tl-2201 cuprate superconductors in high magnetic fields, revealing doping-dependent behaviors and providing constraints for theoretical models of normal state transport.

Contribution

It offers new experimental data on magneto-transport in Tl-2201 at high fields, highlighting differences between optimally doped and overdoped samples.

Findings

Weak magnetic field regime extends to 60T in optimally doped samples.

Overdoped samples exit the weak field regime at high fields.

Data constrains models of normal state transport in cuprates.

Abstract

We present a study of in-plane normal state magneto-transport in single crystal Tl-2201 in 60T pulsed magnetic fields. In optimally doped samples (Tc ~ 80K) the weak-magnetic-field regime extends to fields as high as 60T, but in overdoped samples (Tc ~ 30K) we are able to leave the weak field regime, as shown by the behavior of both the magnetoresistance and the Hall resistance. Data from samples of both dopings provide constraints on the class of model necessary to describe normal state transport in the cuprates.
