Crystalline anisotropy in electron-doped superconductor Pr0.9LaCe0.1CuO4

Abstract We have investigated the c -axis anisotropy of a novel electron-doped single crystal Pr 0.9 LaCe 0.1 CuO 4 ( T c =25.8 K) by means of the magnetic torque. We pay a careful attention to the contribution from the Pr 3+ moments. We obtain the anisotropy parameter 36≲ γ c c -axis anisotropy is concerned, the properties of electron-doped cuprates are very similar to the hole-doped cuprates. The magnetization studies reveal that the irreversible line of Pr 0.9 LaCe 0.1 CuO 4 is much higher than Bi2212. In addition, no second peaks appear in the magnetization curves at various temperatures. We conclude that the c -axis anisotropy in Pr 0.9 LaCe 0.1 CuO 4 is fairly weaker than Bi2212.
