The rare-earth perovskite has been widely used as a substrate for the growth of epitaxial ferroelectric and multiferroic thin films, while its detailed low-temperature magnetic properties were rarely reported. In this paper, we performed detailed magnetization, specific heat, and single crystal neutron scattering measurements, along with the crystalline electric field calculations to study the low-temperature magnetic properties of . All our results suggest the magnetic has an Ising-like pseudo-doublet ground state at low temperatures. Due to the constrain of local point symmetry, these Ising moments are confined in the plane with a tilt angle of to the axis. In zero field, the system undergoes an antiferromagnetic phase transition at K, and forms a noncollinear magnetic structure below . We find the dipole-dipole interactions play an important role to determine the magnetic ground state, which are also responsible for the quasi-one-dimensional magnetism in . The significant anisotropic diffuse scatterings further confirm the quasi-one-dimensional magnetism along the axis. The magnetic phase diagram with the field along the easy axis is well established. In addition to the antiferromagnetic state, there is an exotic field-induced phase emerged near the critical field T, where three-dimensional magnetic order is suppressed but strong one-dimensional correlations may still exist.
