Spintronics in antiferromagnetic helix: A new prescription
Suparna Sarkar, Santanu K. Maiti
The occurrence of a finite mismatch between the up and down spin energy channels due to the application of an electric field, leading to the generation of a polarized spin current…
Circular currents in a magnetic ring with zero net magnetization in presence of a side-coupled one-dimensional chain
Sourav Karmakar, Suparna Sarkar, Santanu K. Maiti
We investigate persistent charge and spin currents in a magnetic quantum ring threaded by an Aharonov-Bohm flux, in the presence of a side-coupled one-dimensional non-magnetic chai…
Spin filtration in a single-stranded antiferromagnetic helix with slowly varying disorder: Higher order electron hopping
Suparna Sarkar, Santanu K. Maiti, David Laroze
This work explores spin filtration in a helical magnetic system within a tight-binding framework, where neighboring magnetic moments are aligned antiparallel. The helix experiences…
Phenomenon of multiple reentrant localization in a double-stranded helix with transverse electric field
Sudin Ganguly, Suparna Sarkar, Kallol Mondal +1
The present work explores the potential for observing multiple reentrant localization behavior in a double-stranded helical (DSH) system, extending beyond the conventional nearest-…
Thermal signature of helical molecule: Beyond nearest-neighbor electron hopping
Suparna Sarkar, Santanu K. Maiti, David Laroze
We investigate, for the first time, the thermal signature of a single-stranded helical molecule that is described beyond usual nearest-neighbor electron hopping, by analyzing elect…
Localization to delocalization transition in a double stranded helical geometry: Effects of conformation, transverse electric field and dynamics
Suparna Sarkar, Santanu K. Maiti
Conformational effect on electronic localization is critically investigated for the first time considering a double-stranded helical geometry (DSHG) subjected to an electric field.…
Spin-selective transmission through a single-stranded magnetic helix
Suparna Sarkar, Santanu K. Maiti
Magnetic helix (MH) structure can be a role model for future spintronic devices. Utilizing the advantage of constructing possible magnetic configurations, in the present work first…
