Manipulating chiral-spin transport with ferroelectric polarization
Xiaoxi Huang, Xianzhe Chen, Yuhang Li +28
A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more t…
Coexisting and interacting spin torque driven free and reference layer magnetic droplet solitons
Sheng Jiang, Sunjae Chung, Martina Ahlberg +6
Magnetic droplets are nanoscale, non-topological, magnetodynamical solitons that can be nucleated in spin torque nano-oscillators (STNOs) or spin Hall nano-oscillators (SHNOs). All…
A coupled magneto-structural continuum model for multiferroic
John Mangeri, Davi Rodrigues, Sudipta Biswas +3
A continuum approach to study magnetoelectric multiferroic (BFO) is proposed. Our modeling effort marries the ferroelectric (FE) phase field method and micromagn…
Layer-dependent optically-induced spin polarization in InSe
Jovan Nelson, Teodor K. Stanev, Dmitry Lebedev +9
Optical control of spin in semiconductors has been pioneered using nanostructures of III-V and II-VI semiconductors, but the emergence of two-dimensional van der Waals materials of…
Twisted bilayers of thin film magnetic topological insulators
Gaurav Chaudhary, Anton A. Burkov, Olle G. Heinonen
Twisted bilayer graphene (TBG) near "magic angles" has emerged as a rich platform for strongly correlated states of two-dimensional Dirac semimetals. Here we show that twisted bila…
DFT+U and Quantum Monte Carlo study of electronic and optical properties of AgNiO and AgNiCoO delafossite
Hyeondeok Shin, Panchapakesan Ganesh, Paul R. C. Kent +5
As the only semimetallic -based delafossite, AgNiO has received a great deal of attention due to both its unique semimetallicity and its antiferromagnetism in the NiO$_…
