We report a study of spin-dependent transport in a system composed of a quantum dot
coupled to a normal metal lead and a ferromagnetic lead (NM-QD-FM). We use the master …

We propose two new approaches for regulating spin polarization and spin inversion in a
conducting junction within a tight-binding framework based on wave-guide theory. The …

Possible engineering of spin polarization through a multistranded magnetic quantum
network in the presence of light irradiation is reported. Each site of the network is associated …

Magnetic helix (MH) structure can be a role model for future spintronic devices. Utilizing the
advantage of constructing possible magnetic configurations, in this work we investigate …

We have studied the current through a carbon-nanotube quantum dot with one
ferromagnetic and one normal-metal lead. For the values of gate voltage at which the normal …

In the present work, we investigate the effect of a laser field on the multiphoton excitation of a
2-D quantum dot with the Kratzer potential under the influence of an external magnetic field …

We report a large degree of spin filtration in a double stranded (ds) antiferromagnetic helix
(AFH) system. Generally spin channel separation is not possible when a magnetic system …

We investigate the spin-flip effect on electronic transport in a nanostructure composed of two
nonmagnetic (NM) leads separated by a periodic spacer. The spacer is composed of one …

We report a spin filtration operation considering an antiferromagnetic helix system,
possessing zero net magnetization. Common wisdom suggests that for such a system, a …

We propose that a magnetic quantum wire composed of magnetic and non-magnetic atomic
sites can be used as a spin filter for a wide range of applied bias voltage. We adopt a simple …
