Giant magnetoresistance in semiconductor / granular film heterostructures with cobalt nanoparticles

open access: yes, 2009
We have studied the electron transport in SiO${}_2$(Co)/GaAs and SiO${}_2$(Co)/Si heterostructures, where the SiO${}_2$(Co) structure is the granular SiO${}_2$ film with Co nanoparticles.

Spin‐Selective Interface Engineering in Oxide–Ferromagnetic Junctions via Atomic‐Scale Oxygen Control

open access: yesAdvanced Science, EarlyView.
We show that interfacial oxygen at the MgO/Fe interface can be transformed from an uncontrolled variable into a tunable design parameter for spintronic junctions. Momentum microscopy provides direct access to the momentum‐ and spin‐resolved electronic structure beneath the insulating MgO layers, revealing how oxygen intercalation reshapes buried Fe ...

Anomalous magnetoresistance in centrosymmetric skyrmion-lattice magnet Gd2PdSi3

open access: yesNew Journal of Physics, 2020
We performed a systematic study of the temperature- and field-dependence of magnetization and resistivity of Gd _2 PdSi _3 , which is a centrosymmetric skyrmion crystal.

Non-monotonic magnetic field and density dependence of in-plane magnetoresistance in dilute two-dimensional holes in GaAs/AlGaAs

open access: yes, 2001
We studied low temperature (T=50mK) in-plane magnetoresistance of a dilute two-dimensional hole system in GaAs/AlGaAs heterostructure that exhibits an apparent metal-insulator transition.

Nonreciprocal Charge Transport in an Iron‐Based Superconductor with Broken Inversion Symmetry Engineered by a Hydrogen‐Concentration Gradient

open access: yesAdvanced Science, EarlyView.
Concentration gradients can serve as a universal platform for breaking spatial inversion symmetry. We demonstrate this concept by observing nonreciprocal electrical transport—a sensitive probe of inversion‐symmetry breaking—in the iron‐based superconductor Sm1111 with an engineered hydrogen gradient.

Universal negative magnetoresistance in antiferromagnetic metals from symmetry breaking of electron wave functions

open access: yesCommunications Materials
Layered van der Waals crystals of topologically non-trivial and trivial semimetals with antiferromagnetic (AFM) ordering of magnetic sublattice are known to exhibit a negative magnetoresistance that is well correlated with AFM magnetization changes in a ...

Negative differential conductance and magnetoresistance oscillations due to spin accumulation in ferromagnetic double-island devices

open access: yes, 2006
Spin-dependent electronic transport in magnetic double-island devices is considered theoretically in the sequential tunneling regime. Electric current and tunnel magnetoresistance are analyzed as a function of the bias voltage and spin relaxation time in

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

open access: yesAdvanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Antilocalization effect on photo-generated carriers in semi-insulating GaAs sample

open access: yesMaterials Research, 2012
Magnetoresistance measurements were performed on an illuminated semi-insulating GaAs sample with intrinsic deep level defects. Electrical carriers were photo-generated under light excitation and positive magnetoresistance for B < 0.2 T was observed in ...
