Field-induced spin-density wave beyond hidden order in URu2Si2
URu2Si2 is one of the most enigmatic strongly correlated electron systems and offers a fertile testing ground for new concepts in condensed matter science. In spite of >30 years of intense research, no consensus on the order parameter of its low-temperature hidden-order phase exists. A strong magnetic field transforms the hidden order into magnetically ordered phases, whose order parameter has ...
متن کاملOn the destruction of the hidden order in URu2Si2 by a strong magnetic field
We present a study of transport properties of the heavy fermion URu2Si2 in pulsed magnetic field. The large Nernst response of the hidden order state is found to be suppressed when the magnetic field exceeds 35 T. The combination of resistivity, Hall and Nernst data outlines the reconstruction of the Fermi surface in the temperature-field phase diagram. The zero-field ground state is a compensa...
متن کاملPressure-Induced Magnetism and Hidden Order in URu2Si2
We discuss the discovery of pressure-induced antiferromagnetism in URu2Si2, in the context of neutron, NMR and μSR results. The identification of a critical pressure separating mean-field and Ising phase transitions leads us to propose that the system lies close to a bicritical point associated with magnetic and (non-magnetic) hidden order. We conclude that the recent observation of an isotropi...
متن کاملSpin-orbit density wave induced hidden topological order in URu2Si2
The conventional order parameters in quantum matters are often characterized by 'spontaneous' broken symmetries. However, sometimes the broken symmetries may blend with the invariant symmetries to lead to mysterious emergent phases. The heavy fermion metal URu2Si2 is one such example, where the order parameter responsible for a second-order phase transition at Th=17.5 K has remained a long-stan...
متن کاملAbsence of a static in-plane magnetic moment in the ‘hidden-order’ phase of URu2Si2
We have carried out a careful magnetic neutron scattering study of the heavy fermion compound URu2Si2 to probe the possible existence of a small magnetic moment parallel to tetragonal basal plane in the ‘hidden-order’ phase. This small in-plane component of the magnetic moment on the uranium sites S‖ has been postulated by two recent models (rank-5 superspin/hastatic order) aiming to explain th...
