Abstract

The rare-earth compounds $R_{2} O_{2} Bi$ $(R = Tb, Dy, Er, Lu, Y)$ are newly discovered superconductors in the vicinity of a rare-earth magnetic long-range order. In this work, we determine the magnetic order of the parent compound ${Dy}_{2} O_{2} Te$ by neutron scattering as the $A$ -type antiferromagnetic structure below the Néel temperature $T_{N} = 9.7 K$ . The large staggered magnetic moment 9.4(1) $μ_{B}$ per Dy at $T = 3.5 K$ lies in the basal $a b$ plane. In a magnetic field, anomalous magnetic properties including the bifurcation between zero-field- and field-cooling magnetization, a butterfly-shaped magnetic hysteresis, and slow magnetic relaxation emerge, which are related to the field-induced metamagnetic transitions in ${Dy}_{2} O_{2} Te$ . Our experimental findings could stimulate further research on the relation between antiferromagnetism and superconductivity in these rare-earth compounds.
