Superconducting and normal state properties of single crystalline RFeAsO-based materials

ORAL

Abstract

We report electrical resistivity, Hall effect, magnetoresistance, magnetization, and specific heat measurements on single crystals of several RFeAsO-based materials (R = rare-earth). We also discuss the effects of lattice compression on the magnetic and superconducting transition temperatures. These single crystal studies benefit from significantly sharper signatures of the transitions, compared to earlier studies on polycrystalline samples.
