Summary: | Although many binary heavy rare-earth alloy systems have been studied extensively, there has been little work reported on the Dy-Lu system. The properties of single-crystal DyxLu1−x films grown by molecular beam epitaxy are reported. SQUID magnetometer and neutron diffraction measurements on samples with x=0.4, 0.5, and 0.6 show that the samples order helimagnetically with Néel temperatures of TN=90, 105, and 120 K, respectively. The helical turn angle was mapped as a function of temperature for each of the three alloys. Magnetic x-ray scattering, the first in an alloy, was observed at the (002)± positions at 15 and 60 K in the x=0.4 sample using resonant exchange scattering of synchrotron radiation at the Dy LIII edge. |
