Cloots, "Kronig-penneyising picture of colossal magnetoresistance
Really 'giant' magnetoresistance
was first observed by the Fert's group for Fe/Cr multilayers in 1988.
Resistivity and magnetoresistance
of degenerate ferromagnetic semiconductors with double exchange".
The spin polarization, SP, and giant magnetoresistance
, GMR, are expressed in terms of the conductance, G, as follows :
This combination of benefits is unprecedented, and it is not achievable using any other existing magnetic sensor technologies, including Anisotropic Magnetoresistance
(AMR), Giant Magnetoresistance
(GMR), or the Hall Effect.
occurs in certain ferrous materials and can be applied as a thin strip to become a resistive element.
Japanese electronic and electrical products manufacturer Toshiba Corporation (Tokyo:6502) (LSE:TOS) is to collaborate with memory semiconductor supplier Hynix Semiconductor Inc (KRX:000660) on the joint development of Spin-Transfer Torque Magnetoresistance
Random Access Memory (MRAM), the two companies announced today.
Quantum theory of tunneling magnetoresistance
in GaMnAs/GaAs/GaMnAs heterostructures, Journal of Magnetism and Magnetic Materials 305(1): 141-146.
Though values of magnetoresistance
depend on field orientation, statistical models we discuss below apply to data from either field orientation.
Possibilities of using the magnetoresistance
sensors and barometric sensors will be verified in the sensor system (Cupec et al.
The topics are synthesis strategies and characterization techniques for non-centro-symmetric inorganic oxide materials, geometrically frustrated magnetic material, lithium ion conduction in oxides, thermoelectric oxides, and magnetoresistance
and half-metallicity in transition metal oxides.
A giant magnetoresistance
(GMR) signal acquisition technology to detect movement, sampling at 2 Khz, as the rod strokes.
As the rod strokes, the sensor uses giant magnetoresistance
(GMR) signal acquisition technology to detect movement, sampling at 2 kHz.
Peter Grunberg of Germany and Albert Fert of France were awarded the Nobel Prize in Physics for discovering Giant Magnetoresistance
The phenomenon, which each of the physicists' teams observed independently in 1988, is called giant magnetoresistance
