Query: Topological Hall effect in the Shastry-Sutherland lattice   We study the classical Heisenberg model on the geometrically frustrated
Shastry-Sutherland (SS) lattice with additional Dzyaloshinskii-Moriya (DM)
interaction in the presence of an external magnetic field. We show that several
noncollinear and noncoplanar magnetic phases, such as the flux, all-in/all-out,
3in-1out/3out-1in, and canted-flux phases are stabilized over wide ranges of
parameters in the presence of the DM interaction. We discuss the role of DM
interaction in stabilizing these complex magnetic phases. When coupled to these
noncoplanar magnetic phases, itinerant electrons experience a finite Berry
phase, which manifests in the form of topological Hall effect, whereby a
non-zero transverse conductivity is observed even in the absence of a magnetic
field. We study this anomalous magneto-transport by calculating the electron
band structure and transverse conductivity for a wide range of parameter
values, and demonstrate the existence of topological Hall effect in the SS
lattice. We explore the role of the strength of itinerant electron-local moment
coupling on electron transport and show that the topological Hall features
evolve significantly from strong to intermediate values of the coupling
strength, and are accompanied by the appearance of a finite spin Hall
conductivity.
