Non-equilibrium spin polarisation via interfacial exchange-field spin filtering

Autor: Muduli, Prasanta, Leo, Naëmi, Xu, Mingran, Zhu, Zheng, Puebla, Jorge, Ortiz, Christian, Isshiki, Hironari, Otani, YoshiChika

A key phenomenon that enables nanoscale spintronic devices is the efficient inter-conversion between spin and charge degrees of freedom. Here, we experimentally demonstrate a pathway to generate current-induced spin polarization at the interface betw

Report

Large spin Hall conductivity in epitaxial thin films of kagome antiferromagnet Mn$_3$Sn at room temperature

Autor: Bangar, Himanshu, Khan, Kacho Imtiyaz Ali, Kumar, Akash, Chowdhury, Niru, Muduli, Prasanta Kumar, Muduli, Pranaba Kishor

Mn$_3$Sn is a non-collinear antiferromagnetic quantum material that exhibits a magnetic Weyl semimetallic state and has great potential for efficient memory devices. High-quality epitaxial $c$-plane Mn$_3$Sn thin films have been grown on a sapphire s

Charge to Spin Conversion in van der Waals Metal NbSe2

Autor: Hoque, Anamul Md., Zhao, Bing, Khokhriakov, Dmitrii, Muduli, Prasanta, Dash1, Saroj P.

Quantum materials with a large charge current-induced spin polarization are promising for next-generation all-electrical spintronic science and technology. Van der Waals metals with high spin-orbit coupling and novel spin textures have attracted sign

Local and nonlocal spin Seebeck effect in lateral Pt-$\mathrm{Cr_2O_3}$-Pt devices at low temperatures

Autor: Muduli, Prasanta, Schlitz, Richard, Kosub, Tobias, Hübner, René, Erbe, Artur, Makarov, Denys, Goennenwein, Sebastian T. B.

We have studied thermally driven magnon spin transport (spin Seebeck effect, SSE) in heterostructures of antiferromagnetic $\alpha$-$\mathrm{Cr_2O_3}$ and Pt at low temperatures. Monitoring the amplitude of the local and nonlocal SSE signals as a fun

Experimentally determined correlation between direct and inverse Edelstein effects at Bi2O3/Cu interface by means of spin absorption method using lateral spin valve structure

Autor: Isshiki, Hironari, Muduli, Prasanta, Kim, Junyeon, Kondou, Kouta, Otani, YoshiChika

Publikováno v: Phys. Rev. B 102, 184411 (2020)

We have experimentally elucidated the correlation between inverse and direct Edelstein Effects (EEs) at Bi2O3/Cu interface by means of spin absorption method using lateral spin valve structure. The conversion coefficient {\lambda} for the inverse EE
