Phys. Rev. Lett. 27, 1385–1388 (1971)Structural and Magnetic Phase Transitions in the Rare-Earth PnictidesSee Also: Erratum Received 16 August 1971; published in the issue dated 15 November 1971 The pnictides, a series of rare-earth group-V intermetallic compounds, have the unique property that these cubic materials distort 2-3°K above the Néel point. We are able to explain this unusual behavior by using a model in which the lattice distortions are driven by quadrupole phase transitions which occur at higher temperatures than the magnetic phase transitions. © 1971 The American Physical Society URL:
