Abstract

A single crystal of La₂CoO_4.15 has been grown by the floating zone method and characterised extensively by bulk magnetisation and neutron diffraction studies. Long range antiferromagnetic order (AFM) is observed below (227.7 ± 0.5) K and at (103 ± 2) K a new AFM phase appears. The low temperature phase transition is associated with a first-order structural phase transition from a high-temperature orthorhombic phase to a low-temperature tetragonal phase.
