Linear magnetoresistance at high magnetic field
Journal of Physics F: Metal Physics, 1983A theory is presented for the linear increase in resistivity, in simple metals, with large magnetic field. In calculating the relaxation time the author shows that the magnetic field introduces symmetry breaking between the out- and backscattering of the electrons by impurities and phonons.

Positive and negative linear magnetoresistance of graphite
Physics Letters A, 2004The magnetoresistance (MR) of bulk graphite with different particle sizes is investigated. The MR of the graphite decreases with the particle size decreases. The graphite with micro-sized particles has a positive MR and exhibits positive linear field dependence of MR at about 50 K, whereas the graphite with particle size of 30.2 nm has a negative MR ...

Large linear magnetoresistance in a bismuth nanoribbon
Applied Physics Letters, 2017We report the observation of large linear magnetoresistance (LMR) in an individual bismuth single crystal nanoribbon synthesized by solvothermal method. The LMR reaches 450% at 2 K and 550% at ∼125 K, and remains as high as 200% at room temperature without any sign of saturation under magnetic field up to 16 T.

The barber pole, a linear magnetoresistive head
IEEE Transactions on Magnetics, 1975A short review of bias methods for the magnetoresistive head (MRH), all based on the rotation of the magnetization, is given, and the properties of the various methods are discussed. A novel bias method is proposed which avoids many disadvantages of the former since it is based on the rotation of the current with the aid of slanted conductors, covering

Linear Magnetoresistance Caused by Sample Thickness Variations
Physical Review Letters, 1981Experiments are presented which show that surface imperfections can give rise to a larger linear magnetoresistance than previously supposed; in fact, large enough to explain many hitherto-unexplained published results. A theoretical model, which takes into account both the finite width of the sample and the Hall fields within it, is shown to describe ...

Linear magnetoresistance effect in lateral magnetic superlattices
Solid State Communications, 2011Abstract Two-dimensional electron gas systems modulated by a lateral magnetic superlattice are proposed and the related magnetoresistance effect is described in this work. It is found that the magnetoresistance (MR) ratio of the given structures depends strongly on the uniform magnetic field, and the peaks of the MR ratio depressed linearly with the ...

Linear magnetoresistance of a metal with holes
Physica Status Solidi (a), 1976An investigation is made of the conductivity of a two component material in a magnetic field using a macroscopic effective medium approach. The model describes spherical inclusions of different conductivity large compared to the mean free path of the electrons.

A contribution to the linear magnetoresistance problem
Solid State Communications, 1977Abstract It is shown that semi-classical transport theory provides an extremely accurate prediction of the limiting high field transverse magnetoresistivities of the compensated metals Cd, Pb and W. These results invalidate those theoretical models based on scattering effects which have been proposed to explain the linear term in the ...
