概要
- 論文の詳細を見る
Jahn–Teller structural phase transitions are examined using a simple Ginzburg–Landau approach. The order parameter representing orbital order is complex for the case of doubly degenerate d-orbital states. We find tricritical behavior in ferromagnet-like orbital order under applied uniaxial stress and in antiferromagnet-like orbital order with varying the strength of the interaction between the two sublattices.
