Neutron diffraction study of the magnetic structure of the intermetallic compound DyRh2Si2

Abstract

A study of the magnetic structure of the intermetallic compound DyRh2Si2 (I4/mmm) was performed using neutron (2.459 Å) diffraction of a powder sample. Below 52 K the diffraction patterns reveal a type I antiferromagnetic structure on the Dy sublattice, with a magnetic moment of 9.9±1 μB per ion along c. The appearance of a weak 001 reflection below 18 K is interpreted as due to canting (∼19 °) of the Dy moment from the c axis.
