Bias Voltage Dependence of Sensing Characteristics in Tunneling Magnetoresistance Sensors

Sensors, 2021
One of the characteristic features of tunneling magnetoresistance (TMR) sensors is a strong influence of bias voltage on tunneling current. Since fundamental sensing characteristics of the sensors are primarily determined by the tunneling current, the ...

Large linear magnetoresistance and magnetothermopower in layered SrZnSb2 [PDF]

Applied Physics Letters, 2012
We report the large linear magnetoresistance (∼300% in 9 T field at 2 K) and magnetothermopower in layered SrZnSb2 crystal with quasi-two-dimensional Sb layers. A crossover from the semiclassical parabolic field dependent magnetoresistance to linear field dependent magnetoresistance with increasing magnetic field is observed.

Nonmonotonic magnetoresistance of a two-dimensional viscous electron-hole fluid in a confined geometry [PDF]

, 2017
Ultra-pure conductors may exhibit hydrodynamic transport where the collective motion of charge carriers resembles the flow of a viscous fluid. In a confined geometry (e.g., in ultra-high quality nanostructures) the electronic fluid assumes a Poiseuille ...

Linearization strategies for high sensitivity magnetoresistive sensors [PDF]

The European Physical Journal Applied Physics, 2015
Ultrasensitive magnetic field sensors envisaged for applications on biomedical imaging require the detection of low-intensity and low-frequency signals. Therefore linear magnetic sensors with enhanced sensitivity low noise levels and improved field detection at low operating frequencies are necessary.

2D transport and weak antilocalization effect in topological semimetal PtBi2 nanoflakes

AIP Advances
The striking anisotropic magnetoresistance and linear magnetoresistance observed in topological semimetals have attracted immense attention owing to their potential in magnetoresistance devices. We investigated the magnetotransport properties of trigonal

Impact of confined LO-phonons on the Hall effect in doped semiconductor superlattices

Journal of Science: Advanced Materials and Devices, 2016
Based on the quantum kinetic equation method, the Hall effect in doped semiconductor superlattices (DSSL) has been theoretically studied under the influence of confined LO-phonons and the laser radiation.

Two dimensional Dirac fermions and quantum magnetoresistance in CaMnBi$_2$

, 2012
We report two dimensional Dirac fermions and quantum magnetoresistance in single crystals of CaMnBi$_2$. The non-zero Berry's phase, small cyclotron resonant mass and first-principle band structure suggest the existence of the Dirac fermions in the Bi ...

Robust linear magnetoresistance in WTe2

, 2015
Unsaturated magnetoresistance (MR) has been reported in WTe2, and remains irrepressible up to very high field. Intense optimization of the crystalline quality causes a squarely-increasing MR, as interpreted by perfect compensation of opposite carriers.

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...

Quantum transport of two-dimensional Dirac fermions in SrMnBi2

, 2012
We report two-dimensional quantum transport in SrMnBi$_2$ single crystals. The linear energy dispersion leads to the unusual nonsaturated linear magnetoresistance since all Dirac fermions occupy the lowest Landau level in the quantum limit.
