Exact nematic and mixed magnetic phases driven by competing orders on the pyrochlore lattice

NiccolÃ² Francini, Lukas Schmidt, Lukas Janssen +1

Pyrochlore magnets are a paradigmatic example of three-dimensional frustrated systems and provide an excellent platform for studying a variety of exotic many-body phenomena, includ…

Ferrimagnetism from quantum fluctuations in Kitaev materials

NiccolÃ² Francini, Pedro M. CÃ´nsoli, Lukas Janssen

Ferrimagnetism appears in the temperature-field phase diagrams of several candidate Kitaev materials, such as the honeycomb cobaltates Na $_{2}$ Co $_{2}$ TeO $_{6}$ and Na $_{3}$ Co $_{2}$ SbO $_{6}$ .…

Ferrimagnetism from triple-q order in Na $_{2}$ Co $_{2}$ TeO $_{6}$

NiccolÃ² Francini, Lukas Janssen

The candidate Kitaev magnet Na $_{2}$ Co $_{2}$ TeO $_{6}$ exhibits a characteristic ferrimagnetic response at low temperatures, with a finite residual magnetization that changes sign at a co…

Higher-Rank Spin Liquids and Spin Nematics from Competing Orders in Pyrochlore Magnets

NiccolÃ² Francini, Lukas Janssen, Daniel Lozano-GÃ³mez

Pyrochlore magnets have proven to provide an excellent arena for the realization of a variety of many-body phenomena such as classical and quantum order-by-disorder, as well as spi…
