Tunnel magnetoresistance (TMR) is a magnetoresistive effect that occurs in a magnetic tunnel junction (MTJ), which is a component consisting of two ferromagnets separated by a thin insulator.If the insulating layer is thin enough (typically a few nanometres), electrons can tunnel from one ferromagnet into the other. Since this process is forbidden in classical physics, the …

Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field.There are a variety of effects that can be called magnetoresistance. Some occur in bulk non-magnetic metals and semiconductors, such as geometrical magnetoresistance, Shubnikov–de Haas oscillations, or the common …

Der GMR-Effekt (englisch giant magnetoresistance; heutzutage auch integriert unter dem Begriff Spintronik) oder Riesenmagnetowiderstand basiert auf einem magnetoresistiven Effekt und wird in Strukturen beobachtet, die aus sich abwechselnden magnetischen und nichtmagnetischen dünnen Schichten mit einigen Nanometern Schichtdicke bestehen. Der Effekt bewirkt, dass der …

Un capteur est un dispositif transformant l'état d'une grandeur physique observée en une grandeur utilisable, telle qu'une tension électrique, une hauteur de mercure, une intensité ou la déviation d'une aiguille. On fait souvent (à tort) la confusion entre capteur et transducteur : le capteur est au minimum constitué d'un transducteur.. Le capteur se distingue de l'instrument de mesure ...

Linear Tape-Open (ou LTO) est une technique de stockage sur bande magnétique au format ouvert.. Elle a été développée à la fin des années 1990, conjointement par HP, IBM et la division magnetic tape de Seagate.Cette dernière entité a pris son indépendance quelques années plus tard, puis est devenue Certance, avant d'être rachetée par Quantum Corporation, qui était elle …

The read heads are TMR (tunneling magnetoresistance) devices, which consist of an insulator sandwiched between two sensitive magnetic materials Magnetic fields from the platter influence the closest magnet, causing electrons to tunnel or travel through the insulator and flip the polarity of the second magnet — thus, "reading" the platter's ...
