Název v původním jazyce

Experimental and theoretical study of magnetic ordering and local atomic polarization in Ru-substituted Lu2Fe17.

Popis výsledku v původním jazyce

The distribution of magnetic moments in the iron-rich intermetallic compound Lu2Fe16.5Ru0.5 with Fe partly substituted by Ru has been investigated. The crystal structure and temperature evolution of the magnetic structure was studied using high resolution and high flux neutron powder diffractometers. In contrast to the parent Lu2Fe17, which transforms on cooling from an antiferromagnetic to a ferromagnetic state, Lu2Fe16.5Ru0.5 is an antiferromagnet below 208 K down to the lowest temperatures. The magnetic polarization at the Lu, Fe and Ru absorption edges was studied by x-ray magnetic circular dichroism (XMCD) on single crystal in magnetic field of 3 T, i.e., above the field-induced metamagnetic transition. The Ru XMCD signal proves the existence of induced magnetic polarization parallel to the dominant Fe sublattice magnetization. A corresponding theoretical analysis is provided.
