In contrast to magnetic order formed by electrons' dipolar moments, ordering phenomena associated with higher-order multipoles (quadrupoles, octupoles, etc.) are more difficult to characterize because of the limited choice of experimental probes that can distinguish different multipolar moments. The heavy-fermion compound CeB6 and its La-diluted alloys are among the best-studied realizations of the long-range-ordered multipolar phases, often referred to as "hidden order". Previously the hidden… 

Neutron-scattering studies of spin dynamics in pure and doped CeB6

As a simple cubic system with only one f electron per cerium ion, CeB6 is of model character to investigate the interplay of orbital phenomena with magnetism. It is also a textbook example of a

Evolution of the propagation vector of antiferroquadrupolar phases in Ce3Pd20Si6 under magnetic field

Hidden-order phases that occur in a number of correlated f-electron systems are among the most elusive states of electronic matter. Their investigations are hindered by the insensitivity of standard

Intertwined dipolar and multipolar order in the triangular-lattice magnet TmMgGaO4

It is shown that TmMgGaO4 has multipolar order that can be inferred by inelastic neutron scattering and modeled by transverse field Ising model, and it is demonstrated that the observed unusual spin correlations and thermodynamics can be accurately described by a transverseField Ising models on the triangular lattice with an intertwined dipolar and ferro-multipolar order.

"Hidden order" and its quantum excitations in the triangular-lattice magnet TmMgGaO$_4$

A phase transition is often accompanied by the appearance of an order parameter and symmetry breaking. Certain magnetic materials exhibit exotic hidden-order phases, in which the order parameters are

It is argued that the unusual physical picture of ESR in CeB6 may be strongly affected by spin fluctuations and dynamic collective effects predominantly pronounced in [100] direction.

CeB(6) is a model compound exhibiting antiferroquadrupolar (AFQ) order, its magnetic properties being typically interpreted within localized models. More recently, the observation of strong and sharp

Spin exciton formation inside the hidden order phase of CeB6.

An alternative theory based on a fourfold degenerate Anderson lattice model, including both order parameters as particle-hole condensates of itinerant heavy quasiparticles, explains in a natural way the appearance of the spin exciton resonance and the momentum dependence of its spectral weight, in particular, around the AFQ vector and its rapid disappearance in the disordered phase.

Resonant magnetic exciton mode in the heavy-fermion antiferromagnet CeB6

An unexpected commonality between the two disparate ground states indicates the dominance of itinerant spin dynamics in the ordered low-temperature phases of CeB(6) and throws new light on the interplay between antiferromagnetism, superconductivity and 'hidden' order parameters in correlated-electron materials.
