Magnetic Field Effect on Static Antiferromagnetism in Electron-Doped Superconductor Pr${}_{1-x}$LaCe${}_x$CuO${}_4$ ($x$=0.11 and 0.15)

Abstract

Effects of magnetic fields (applied along the c-axis) on static spin correlation were studied for the electron-doped superconductors Pr${}_{1-x}$LaCe${}_x$CuO${}_4$ with $x$=0.11 ($T_c$=26 K) and $x$=0.15 ($T_c$=16 K) by neutron scattering measurements. In the $x$=0.11 sample located near the antiferromagnetic(AF) and superconducting phase boundary, the field dependence of both the magnetic intensity at T=3 K and the onset temperature of the magnetic order exhibits a peak at $\sim$5 T. In contrast, in the overdoped $x$=0.15 sample a static AF order is neither observed at zero-field nor induced by the field up to 8.5 T. Difference and similarity of the field effect between the hole- and electron-doped high-$T_c$ cuprates are discussed.
