# Interplay between spin-density wave and induced local moments in URu2Si2

@article{Mineev2005InterplayBS, title={Interplay between spin-density wave and induced local moments in URu2Si2}, author={Vladimir P. Mineev and M. E. Zhitomirsky}, journal={Physical Review B}, year={2005}, volume={72} }

Theoretical model for magnetic ordering in the heavy-fermion metal URu2Si2 is suggested. The 17.5 K transition in this material is ascribed to formation of a spin-density wave SDW , which develops due to a partial nesting between electron and hole parts of the Fermi surface and has a negligibly small form factor. Staggered field in the SDW state induces tiny antiferromagnetic order in the subsystem of localized singletsinglet levels. Unlike the other models, our scenario is based on coexistence…

Shubnikov-de Haas oscillations reveal at high fields an abrupt reconstruction of the Fermi surface within the hidden-order (HO) phase of URu2Si2, suggesting an increase in the effective carrier density and suggesting that the field suppression of the HO state is ultimately related to destabilizing a gap in the spectrum of itinerant quasiparticles.

The measured magnetic field dependence of the ordered antiferromagnetic moment and the magnetic excitations in the heavy-fermion superconductor URu2Si2 for fields up to 17 T applied along the tetragonal c axis suggests that the moment m is connected to a hidden order parameter psi which belongs to the same irreducible representation breaking time-reversal symmetry.
