The trend of the tunneling magnetoresistance
(TMR) is due to the spin-orbit scattering in the superconductor.
That also achieved high magnetoresistance
, but the fabrication method "is not good for mass-production," Yuasa admits.
The book also discusses the effects of magnetic fields on spin-based device performance, highlighting effects such as giant magnetoresistance
Temperature control for the measurements can be achieved using a resistive thermometer, which has a low magnetoresistance
effect, or a capacitance thermometer, which has a very low magnetoresistance
These so-called giant magnetoresistance
heads change their resistance at room temperature by about 5 percent in the presence of a magnetic bit of data, says Stuart A.
MDT) will showcase its lineup of advanced Tunneling Magnetoresistance
(TMR) magnetic sensors, including ultra-low power TMR magnetic switches, TMR linear sensors, TMR angle sensors, TMR gear tooth sensors, and the recently announced family of TMR magnetic pattern recognition sensors.
Among the reprinted reports are mechanisms of anti-ferromagnetism in dilute alloys, the theory of the residual resistivity anomaly in potassium, open-orbit effects in thermal magnetoresistance
, and broken symmetry in simple metals.
The second volume switches focus towards photonic materials and devices and includes 12 chapters discussing such topics as organic nonlinear optical crystals and single-crystalline thin films, organic semiconducting thin films, organic random lasers, nonlinear optical properties of organometallic and metalloorganic compounds, nonlinear optical responses and photoinduced electron transfer process in phthalocyanines and related compounds, liquid crystal diffractive optical elements, magnetoresistance
and spin effects in organic light-emitting diodes, and photoinduced transfer between electron donors and fullerenes as unique electron acceptors.
The recent discovery of huge magnetoresistance
effects in the manganese oxide class of materials (such as L[a.
It will make use of a property known as giant magnetoresistance
This collaboration, centered on studies of magnetic metal multilayers, led to the discovery of the Giant Magnetoresistance
effect (GMR) in 1988.
The main objectives of the project are: i) the synthesis and characterization of several high-quality soluble functionalized graphene materials, having different organic functional molecules; ii) the tuning of the magnetoresistance
by means of chemical design, introducing electronically active molecules and controlling the surface functionalization; iii) the photoswitching of the electronic properties such as electrical conductivity by covalent azobenzene derivatization; iv) the development and characterization of thin films of defective-free graphene through molecular recognition of functionalized graphenes; and v) the synthesis of magnetic nanoparticles/magnetic clusters-graphene hybrids for the room temperature tuning of magnetic properties on surfaces.
STUDY GOALS AND OBJECTIVES In 2007, the Nobel Prize Committee stated that, "Giant magnetoresistance
(GMR) can be considered one of the first real applications of the promising field of nanotechnology.
The text also expands coverage of techniques used to characterize solids and includes updated sections on such hot topics as fuel cells, organic polymers, organic superconductors, fullerenes, photonics, and giant and colossal magnetoresistance
The present generation of computer hard-disk drives uses a read-head based on giant magnetoresistance
(GMR) thin films.
