Robust negative longitudinal magnetoresistance and spin–orbit torque in sputtered Pt3Sn and Pt3SnxFe1-x topological semimetal

Nature Communications, 2023
Contrary to topological insulators, topological semimetals possess a nontrivial chiral anomaly that leads to negative magnetoresistance and are hosts to both conductive bulk states and topological surface states with intriguing transport properties for ...

Giant linear magnetoresistance in half-metallic Sr2CrMoO6 thin films

npj Quantum Materials, 2021
Linear magnetoresistance (LMR) is a special case of a magnetic-field induced resistivity response, which has been reported in highly disordered semiconductor systems and in topological materials.

Possible scale invariant linear magnetoresistance in pyrochlore iridates Bi2Ir2O7

New Journal of Physics, 2019
We report the observation of a linear magnetoresistance in single crystals and epitaxial thin films of the pyrochlore iridate Bi _2 Ir _2 O _7 . The linear magnetoresistance is positive and isotropic at low temperatures, without any sign of saturation up

B^{2} to B-linear magnetoresistance due to impeded orbital motion

Physical Review Research, 2022
Strange metals exhibit a variety of anomalous magnetotransport properties, the most striking of which is a resistivity that increases linearly with magnetic field B over a broad temperature and field range. The ubiquity of this behavior across a spectrum

Linear magnetoresistance in mosaic-like bilayer graphene [PDF]

Nature Physics, 2015
Contrary to common belief, bilayer graphene is not defect-free: the abundance of partial dislocations leads to a mosaic-like network structure. As a result, as now shown, the magnetoresistance of bilayer graphene depends linearly, rather than quadratically, on the external magnetic field.

Large magnetoresistance effect in nitrogen-doped silicon

AIP Advances, 2017
In this work, we reported a large magnetoresistance effect in silicon by ion implantation of nitrogen atoms. At room temperature, the magnetoresistance of silicon reaches 125 % under magnetic field 1.7 T and voltage bias -80 V. By applying an alternating

Large linear non-saturating magnetoresistance and high mobility in ferromagnetic MnBi

Nature Communications, 2021
Ferromagnetic systems rarely display a large or non-saturating magnetoresistance, due to the low Fermi velocity of the predominant charge carrier. Here, the authors show that MnBi, a ferromagnet, bucks this trend, showing both large and non-saturating ...

Current Jets, Disorder, and Linear Magnetoresistance in the Silver Chalcogenides [PDF]

Physical Review Letters, 2005
The inhomogeneous distribution of excess or deficient silver atoms lies behind the large and linear transverse magnetoresistance displayed by Ag2+/-delta Se and Ag2+/-delta, introducing spatial conductivity fluctuations with length scales independent of the cyclotron radius.

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.
