Abstract
Effects of magnetic fields (applied along the c axis) on static spin correlation were studied for the electron-doped superconductors Pr1−xLaCexCuO4 with x=0.11 (Tc=25 K) and x=0.15 (Tc=16 K) by neutron-scattering measurements. In the x=0.11 sample, which is located near the antiferromagnetic (AF) and superconducting phase boundary, a commensurate magnetic order develops below around Tc at zero field. Upon applying a magnetic field up to 9 T both the magnetic intensity and the onset temperature of the order increase with the maximum field effect at ∼5 T. In contrast, in the overdoped x=0.15 sample any 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-Tc cuprates are discussed.
