Abstract

ErCrO₄ has been synthesized as a single phase by the nitrate precursor method under an oxygen flow at 753 K. The structure of this compound has been refined from X-ray and neutron powder diffraction data, showing the zircon-type structure, S.G. I4₁/amd and lattice parameters a=7.062(1) Å, c=6.201(3) Å. Magnetic susceptibility and magnetization measurements reveal the existence of incipient ferromagnetic interactions in the Cr⁵⁺ sublattice below 25 K. When the temperature decreases, the superexchange Er³⁺-O-Cr⁵⁺-O-Er³⁺ antiferromagnetic interactions become predominant. The estimated Néel temperature is 15 K. A metamagnetic transition has been detected at the critical field of 375 Oe. Neutron diffraction data show a three-dimensional antiferromagnetic ordering in which both Cr⁵⁺ and Er³⁺ sublattices are involved. Such ordering takes place with a propagation vector k=[0].
