Negative Differential Resistance and Ultra-High TMR in Altermagnetic Tunnel Junctions
Sajjan Sheoran, Luke Keenan, Declan Nell +1
Altermagnets can replace ferromagnets in tunnel junctions, yielding large tunneling magnetoresistance, ultrafast switching, and low-power functionality. While most studies explore…
A non-equilibrium quantum transport framework for spintronic devices with dynamical correlations
Declan Nell, Milos Radonjic, Ivan Rungger +3
Two-terminal spintronic devices remain challenging to model under realistic operating conditions, where the interplay of complex electronic structures, correlation effects and bias…
Non-equilibrium correlation effects in spin transport through the 2D ferromagnet FeGeTe
Declan Nell, Stefano Sanvito, Andrea Droghetti
Understanding non-equilibrium spin transport through 2D ferromagnets is a theoretical challenge, as correlations produce a complex electronic structure with coexisting itinerant an…
Spin-dependent transport in FeGaTe and FeGeTe (=3-5) van der Waals ferromagnets for magnetic tunnel junctions
Anita Halder, Declan Nell, Akash Bajaj +2
We present a systematic first-principles investigation of linear-response spin-dependent quantum transport in the van der Waals ferromagnets FeGeTe, FeGeTe, FeG…
