Spin and orbital ordering in Y1-xLaxVO₃
Abstract
The spin and orbital ordering in Y1-xLaxVO₃ (0.30 ≤ x ≤ 1.0) has been studied to map out the phase diagram over the whole doping range 0 ≤ x ≤ 1. The phase diagram is compared with that for RVO₃ (R = rare earth or Y) perovskites without A-site variance. For x > 0.20, no long-range orbital ordering was observed above the magnetic ordering temperature TN; the magnetic order is accompanied by a lattice anomaly at a Tt ≤ TN as in LaVO₃. The magnetic ordering below Tt ≤ TN is G type in the compositional range 0.20 ≤ x ≤ 0.40 and C type in the range 0.738 ≤ x ≤ 1.0. Magnetization and neutron powder diffraction measurements point to the coexistence below TN of the two magnetic phases in the compositional range 0.4 < x < 0.738. Samples in the compositional range 0.20 < x ≤ 1.0 are characterized by an additional suppression of a glasslike thermal conductivity in the temperature interval TN < T < T* and a change in the slope of 1/χ(T). We argue that T* represents a temperature below which spin and orbital fluctuations couple together via λL∙S.
