Multicritical points in a model for 5f-electron systems under pressure and magnetic field
Chaura, Julián Alberto Faúndez; Magalhaes, Sergio Garcia; Calegari, Eleonir João; Riseborough, Peter S. (2021) [Artículo de periódico] -
Unfolding of antiferromagnetic phases and multicritical points in a two-orbital model for uranium compounds under pressure and magnetic field
Magalhaes, Sergio Garcia; Lausmann, Ana Claudia; Calegari, Eleonir João; Riseborough, Peter S. (2020) [Artículo de periódico]We investigate the occurrence of multicritical points under pressure and magnetic field in a model that describes two 5 f bands (of either α or β characters), which hybridize with a single itinerant conduction band. The 5 ... -
Unusual magnetic field-dependence of a possible hidden order phase
Calegari, Eleonir João; Magalhaes, Sergio Garcia; Riseborough, Peter S. (2017) [Artículo de periódico]URu2Si2 exhibits a second-order phase transition at 17.5 K. Initially it was thought that the transition was to a spin density wave phase, however, subsequent measurements do not support this assignment. Despite the unknown ...
