Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr2S3‐2D

Advanced Materials, EarlyView.
Interfacial electron donation from graphene redistributes charge within single‐layer Cr2S3‐2D, preferentially accumulating at the lower Cr/S plane. The resulting minute magnetic imbalance lifts the equivalence of the two magnetic sublayers, enabling atomic‐resolution identification and field‐induced control of Néel‐vector states in a two‐dimensional A ...

Designing for children’s reflections in collaborative interaction mediated by technology: A systematic literature review

, 2021
Reflection is an integral part of collaborative interaction. However, we know little about how to design for reflection in collaborative activities mediated by technologies.

The phase diagram of the Heisenberg antiferromagnet with four-spin interactions [PDF]

Journal of Physics: Condensed Matter, 2009
We study the quantum phase diagram of the Heisenberg planar antiferromagnet with a subset of four-spin ring exchange interactions, using the recently proposed heirarchical mean-field approach. By identifying relevant degrees of freedom, we are able to use a single variational anzatz to map the entire phase diagram of the model and uncover the nature of

Spectrally Programmable Spin‐Polarized Photocurrents in WSe2–NiPS3 Magnetic van der Waals Heterostructures

Advanced Materials, EarlyView.
Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central

Spin Transport Across Interfaces With the Non‐Collinear Antiferromagnet Mn3Sn

Advanced Materials, EarlyView.
We study spin transport with Mn3Sn|Metal${\rm Mn}_3{\rm Sn}\vert{\rm Metal}$ heterostructures. For Mn3Sn|Pt${\rm Mn}_3{\rm Sn}\vert{\rm Pt}$ heterostructures, ultrafast spin current generation by optical pumping of Mn3Sn${\rm Mn}_3{\rm Sn}$ is explored, while for Mn3Sn|NiFe${\rm Mn}_3{\rm Sn}\vert{\rm NiFe}$ heterostructures, we probe the spin–charge ...

Dzyaloshinskii-Moriya Interaction across an Antiferromagnet-Ferromagnet Interface

Physical Review Letters, 2017
The antiferromagnet (AFM) / ferromagnet (FM) interfaces are of central importance in recently developed pure electric or ultrafast control of FM spins, where the underlying mechanisms remain unresolved. Here we report the direct observation of Dzyaloshinskii Moriya interaction (DMI) across the AFM/FM interface of IrMn/CoFeB thin films.
