Classical and quantum routes to linear magnetoresistance

Nature Materials, 2008
The hallmark of materials science is the ability to tailor the microstructure of a given material to provide a desired response. Carbon mixed with iron provides the steel of buildings and bridges; impurities sprinkled in silicon single crystals form the raw materials of the electronics revolution; pinning centres in superconductors let them become ...

Magnetoresistive thick film sensor for linear displacements

Sensors and Actuators A: Physical, 1995
Abstract A new thick film material has been developed starting from Ni and Co powders in the ratio Ni:Co = 3:1. The thermal treatment (in N2, up to 950 °C) of the metal films deposited on glazed alumina enables the in situ formation of the NiCo alloy.

Search for linear magnetoresistance in aluminum

Solid State Communications, 1974
Abstract The induced torque from high-purity aluminum for magnetic field rotation in a (100) plane exhibits little high-field linear magnetoresistance except for a narrow angular region (±3°) around 〈100〉 directions. The dimensionless slope of the high-field magnetoresistance determined from the induced torque is up to 25 times smaller than that ...

Linear magnetoresistance of a metal with holes

Physica Status Solidi (a), 1976
An 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.

Linear magnetoresistance of potassium

Journal of Physics C: Solid State Physics, 1970
Measurements of the linear magnetoresistance effect in pure potassium were made using two independent methods. Four-terminal measurements on straight narrow samples showed transverse and longitudinal effects of the same magnitude. An induced torque method was then used on large good single crystals.

Quantum linear magnetoresistance

Europhysics Letters (EPL), 2000
A description is presented of experimental results, old and new ones, in which a magnetoresistance was discovered, linear in magnetic field. It is explained that there are two theoretical possibilities for such a phenomenon. The first one happens in a polycrystalline metal in a classically large field; it was known since the late 1950s.

Magnetism and linear field magnetoresistivity in UPt3

Physica B: Condensed Matter, 1990
Abstract The temperature dependence of the transverse magnetoresistivity (upto 7.6 tesla) for heavy fermion UPt3 has been studied The linear term in the field dependence of resistivity is found to decrease with increasing temperature and vanishes for T> 6 K.

A contribution to the linear magnetoresistance problem

Solid State Communications, 1977
Abstract 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 ...

Linear field amplification for magnetoresistive sensors

Journal of Applied Physics, 2008
In this article, we describe the fabrication and characterization of a spin valve (SV) magnetoresistive (MR) sensor, located in the gap of two magnetically soft flux guides (FGs) that enhance the sensor magnetic field sensitivity, while keeping in the sensor a quasilinear Barkhausen-noise-free response.

Linear Magnetoresistance in the Quantum Limit in Graphite

Physical Review, 1968
Measurements of the galvanomagnetic properties of single-crystal graphite were made at 4.2\ifmmode^\circ\else\textdegree\fi{}K in pulsed magnetic fields up to 160 kG. With the magnetic field parallel to the $c$ axis, the transverse magnetoresistance is approximately proportional to the magnetic field strength, and the Hall coefficient is constant above
