Golam's recent paper entitled "Tuning Dzyaloshinskii-Moriya interaction in ferrimagnetic GdCo: A first-principles approach (link)" published in PRB. In this article, we explore the impact of cap layer composition and different cap layer heavy metals on the Dzyaloshinskii-Moriya Interaction (DMI). We also show the effect of structural arrangements (to mimic the experimentally realistic structures) on the DMI.

Hamed's recent paper entitled "Self-focusing hybrid skyrmions in spatially varying canted ferromagnetic systems (link)" published in PRB.

Yunkun's recent paper got accepted. This research on Skyrmionns will improve memory at the nanoscale.

Yunkun's paper entitled "Anatomy of nanomagnetic switching at a 3D topological insulator PN junction (link)" published in Scientific Reports. In this paper, Y. Xie et al. analyze how spins filtered at an in-plane topological insulator PN junction (TIPNJ) interact with a nanomagnet, and argue that the intrinsic charge-to-spin conversion does not translate to an external gain if the nanomagnet also acts as the source contact.

Golam's paper entitled "A Deep Dive Into the Computational Fidelity of High-Variability Low Energy Barrier Magnet Technology for Accelerating Optimization and Bayesian Problems (link)" published in IEEE Magnetics Letters. In this paper, G. Morshed et al. show the impact of non-idealities on computational networks built from low-barrier magnets (LBMs).

Golam's paper entitled "Choose your tools carefully: a comparative evaluation of deterministic vs. stochastic and binary vs. analog neuron models for implementing emerging computing paradigms (link)" published in Frontiers in Nanotechnology. In this paper, G. Morshed et al. show a comparative analysis between analog and binary neuron models (including stochasticity) for analog time-series prediction tasks.

Hamed's paper entitled "Low Power In-Memory Computation with Reciprocal Ferromagnet/Topological Insulator Heterostructures (link)" published in ACS Nano. In this paper, H. Vakili et al. show the use of two ferromagnet (FM)/topological insulation (TI) heterostructures to design an integrated 1-transistor 1-magnetic tunnel junction magnetic (1T-1MTJ) random access memory unit (MRAM) for an ultra-low power Processing-in-Memory (PiM) architecture.

Jianhua's recent paper entitled "Computational investigation of half-Heusler/MgO magnetic tunnel junctions with (001) orientation (link)" published in JAP.

VINO member Golam Morshed has been awarded the 2023-24 Endowed Graduate Fellowships (Olsen Fellowship) by UVA Engineering based on academic excellence and demonstrated scholarship. Congrats to Golam!

Golam's co-authored paper (led by Quessab et al. at NYU) entitled "Interplay between Spin-Orbit Torques and Dzyaloshinskii-Moriya Interactions in Ferrimagnetic Amorphous Alloys (link)" published in Advanced Science. In this paper, we investigate a simultaneous control of spin-orbit torques (SOTs) and Dzyaloshinskii-Moriya interactions (DMI) in amorphous ferrimagnetic alloys to pave the way for energy-efficient current-induced domain wall or skyrmion motion.
