Spin valve transistor is different from conventional transistor. In this for conduction we use spin polarization of electrons. Only electrons with correct spin polarization can travel successfully through the device. APPLICATIONS Spin transistors have huge potential for incorporation in stable, high sensitivity magnetic field sensors forready shown its strength in applications such as read heads and magnetic random access memories (MRAMs). Driven by such lowfield applications, a search for higher sensi state spinvalve transistor (SVT) structure as a spectroscopic tool to investigate transport properties of the CPP spinvalve effect and spin valve transistor applications

Depending on the magnetic configuration of the spin valve, the electrical signal is transmitted (bottom) or suppressed (top). Credit: Joel Cramer This is a huge step towards the spin transistor that is needed to construct spintronic devices. Magnon circular rotation of spin waves and its applications

Download Citation Combining ferromagnetic and semiconductor materials is a challenging route to create new options for electronic devices in which the spin of the electron is employed. The spinvalve transistor (SVT) is the first of such hybrid devices shown to work successfully. This review In 1995 the solidstate spinvalve transistor measuring the CPP spinvalve effect was introduced. This device made it possible to circumvent the low resistance dilemma, and so made CPPGMR applicable in sensor applications.spin valve transistor applications The spinvalve transistorSVT! , introduced in 1995, is a device in which ferromagnets and semiconductors have been tightly integrated, and both materials are essential in
