Abstract
This paper presents a study of the magnetoresistance of several single crystals of high-purity thallium in magnetic fields up to 100 kG at liquid-helium temperatures. The experimental results are interpreted in terms of Soven's relativistic orthogonalized-plane-wave model for the Fermi surface of thallium. At low fields the magnetoresistance is in better agreement with the model than was previous work, while no evidence is found for an open orbit parallel to [0001]. Detailed results up to 54 kG are consistent with the model if incomplete magnetic breakdown is assumed and high-field results show that breakdown is not complete below 100 kG.
