Atomic scale skyrmions and large topological Hall effect in a breathing-kagome lattice
Nyayabanta Swain, Munir Shahzad, Pinaki Sengupta
Motivated by recent experiments in GdRuAl, we demonstrate the emergence of atomic scale Skyrmions in interacting spins on a breathing kagome lattice with competing n…
Skyrmion-driven topological Hall effect in a Shastry-Sutherland magnet
N. Swain, M. Shahzad, G. V. Paradezhenko +3
The Shastry-Sutherland model and its generalizations have been shown to capture emergent complex magnetic properties from geometric frustration in several quasi-two-dimensional qua…
Phase Diagram of a Spin-ice Kondo Lattice Model in a Breathing Pyrochlore Lattice
Munir Shahzad, Kipton Barros, Stephanie H. Curnoe
We study a spin-ice Kondo lattice model on a breathing pyrochlore lattice with classical localized spins. The highly efficient kernel polynomial expansion method, together with a c…
Complex magnetic ordering and associated topological Hall effect in a two-dimensional metallic chiral magnet
Nyayabanta Swain, Munir Shahzad, Pinaki Sengupta
Motivated by recent experiments on the observation of room temperature skyrmions in a layered heterostructure and subsequent demonstration of topological Hall effect in the same sy…
Topological Hall effect in the Shastry-Sutherland lattice
Munir Shahzad, Nyayabanta Swain, Pinaki Sengupta
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…
Phase Diagram of the Shastry-Sutherland Kondo Lattice Model with Classical Localized Spins: A Variational Calculation Study
Munir Shahzad, Pinaki Sengupta
We study the Kondo lattice Shastry-Sutherland model with additional Dzyaloshinskii-Moriya(DM) interactions, exploring the possible magnetic phases in its multi-dimensional paramete…
Noncollinear magnetic ordering in a frustrated magnet: Metallic regime and the role of frustration
Munir Shahzad, Pinaki Sengupta
We explore the magnetic phases in a Kondo lattice model on the geometrically frustrated Shastry-Sutherland lattice at metallic electron densities, searching for noncollinear and no…
Noncollinear magnetic ordering in the Shastry-Sutherland Kondo lattice model: Insulating regime and the role of Dzyaloshinskii-Moriya interaction
Munir Shahzad, Pinaki Sengupta
We investigate the necessary conditions for the emergence of complex, noncoplanar magnetic configurations in a Kondo lattice model with classical local moments on the geometrically…
