The effect of annealing to the transport and magnetic properties of electron-doped Pr$_{0.88}$LaCe$_{0.12}$CuO$_{4}$

ORAL

Abstract

The single crystals of electron doped cuprate Pr$_{0.88}$LaCe$_{0.12}$CuO$_{4+\delta}$ have been grown by floating-zone method. As-grown, the samples exhibit long-range antiferromagnetic order without superconductivity. Superconductivity only appears after annealing the sample in pure Ar or vacuum. We present a detailed investigation on how annealing conditions affect the in-plane and $c$-axis resistivity and hall coefficients. We will also discuss the chemical compositions of these samples before and after annealing.
