Berry Curvature and Topological Hall Effect in Magnetic Nanoparticles
Ahsan Ullah, Balamurugan Balasubramanian, Bibek Tiwari +4
Analytical calculations and micromagnetic simulations are used to determine the Berry curvature and topological Hall effect (THE) due to conduction electrons in small ferromagnetic…
Topological phase transitions and Berry-phase hysteresis in exchange-coupled nanomagnets
Ahsan Ullah, Xin Li, Yunlong Jin +6
Topological phase in magnetic materials yields a quantized contribution to the Hall effect known as the topological Hall effect, which is often caused by skyrmions, with each skyrm…
Interplay between magnetism and band topology in Kagome magnets MnSn
Y. Lee, R. Skomski, X. Wang +9
Kagome-lattice magnets MnSn recently emerged as a new platform to exploit the interplay between magnetism and topological electronic states. Some of the most exciting fe…
Chiral Spin Bobbers in Exchange-Coupled Hard-Soft Magnetic Bilayers
Xiaohang Zhang, Tieren Gao, Lei Fang +11
The spin structure of exchange-coupled MnBi:Co-Fe bilayers is investigated by X-ray magnetic circular dichroism (XMCD), polarized neutron reflectometry (PNR), and micromagnetic sim…
Inverse magnetocaloric effect in synthetic antiferromagnets
D. M. Polishchuk, M. Persson, M. M. Kulyk +5
The magnetocaloric effect in exchange-coupled synthetic-antiferromagnet multilayers is investigated experimentally and theoretically. We observe a temperature-controlled inversion…
Simulation of alnico coercivity
Liqin Ke, Ralph Skomski, Todd D. Hoffmann +6
Micromagnetic simulations of alnico show substantial deviations from Stoner-Wohlfarth behavior due to the unique size and spatial distribution of the rod-like Fe-Co phase formed du…
Novel Exotic Magnetic Spin-order in Co5Ge3 Nano-size Materials
Mohammad Salehi-Fashami, Ralph Skomski, Balamurugan Balasubramanian +2
The Cobalt-germanium (Co-Ge) is a fascinating complex alloy system that has unique structure and exhibit range of interesting magnetic properties which would change when reduce to…
Magnetism of Ta Dichalcogenide Monolayers Tuned by Strain and Hydrogenation
Priyanka Manchanda, Vinit Sharma, Hongbin Yu +2
The effects of strain and hydrogenation on the electronic and magnetic properties of monolayers of Ta based dichalcogenides (TaX2; X = S, Se, Te) are investigated using density-fun…
Structural and magnetic properties of Pr-alloyed MnBi nanostructures
P. Kharel, V. R. Shah, X. Z. Li +4
The structural and magnetic properties of Pr-alloyed MnBi (short MnBi-Pr) nanostructures with a range of Pr concentrations have been investigated. The nanostructures include thin f…
Ultrathin BaTiO3 templates for multiferroic nanostructures
Xumin Chen, Seolun Yang, Ji-Hyun Kim +11
Structural, electronic and dielectric properties of high-quality ultrathin BaTiO3 films are investigated. The films, which are grown by ozone-assisted molecular beam epitaxy on Nb-…
