A reversible transition was observed at around 650^°C in both dc electrical resistivity (ρ) and dc magnetic susceptibility (χ) measurements. The transition was characterized by a shoulder-like increment in the p-T curve and a sudden change in the temperature gradient of χ, which is interpreted as the orthorhombic-to-tetragonal transition.

Keywords: Electrical resistivity, magnetic susceptibility, phase transition.
