Abstract

A minimal model for multipole orders in CeB6 shows that the degeneracy of the quadrupole order parameters and strong spin-orbit coupling lead to peculiar temperature and magnetic-field dependences of the X-ray reflection intensity at superlattice Bragg points. Furthermore, the intensity depends sensitively on the surface direction. These theoretical results explain recent X-ray experiments in phases II and III of CeB6. It is predicted that under weak magnetic fields perpendicular to the (111) surface, reflection intensity should change nonmonotonically as a function of temperature.
