Phase diagram of magnetic Skyrmions on three-dimensional lattices and the toroidal antiSkyrmion
Niccolò Francini, Stefano Bolognesi, Sven Bjarke Gudnason +1
Magnetic Skyrmions are planar solitons stabilized by the Dzyaloshinskii-Moriya interaction (DMI) and realized in chiral magnets. We study their natural three-dimensional generaliza…
Exact nematic and mixed magnetic phases driven by competing orders on the pyrochlore lattice
Niccolò 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
Niccolò Francini, Pedro M. Cônsoli, Lukas Janssen
Ferrimagnetism appears in the temperature-field phase diagrams of several candidate Kitaev materials, such as the honeycomb cobaltates NaCoTeO and NaCoSbO.…
Ferrimagnetism from triple-q order in NaCoTeO
Niccolò Francini, Lukas Janssen
The candidate Kitaev magnet NaCoTeO 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
Niccolò Francini, Lukas Janssen, Daniel Lozano-Gómez
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…
