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…
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 Hexagonal Mn1.5X0.5Sn (X = Cr, Mn, Fe, Co) Nanomaterials
R. Fuglsby, P. Kharel, W. Zhang +3
Mn1.5X0.5Sn (X = Cr, Mn, Fe, Co) nanomaterials in the hexagonal Ni2In-type crystal structure have been prepared using arc-melting and melt spinning. All the rapidly quenched Mn1.5X…
Phase stability and Nucleation effect upon Iron addition to SmCo5 bulk magnets
Bhaskar Das, Balamurugan Balasubramanian, David J. Sellmyer
Change in structure and magnetic properties of SmCo5-xFex permanent magnets for different values of x ranging from 0 to 2 have been studied. Structural investigation from X-ray dif…
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…
Transport Spin Polarization of High-Curie Temperature MnBi Films
P. Kharel, P. Thapa, P. Lukashev +4
We report on the study of the structural, magnetic and transport properties of highly textured MnBi films with the Curie temperature of 628K. In addition to detailed measurements o…
