Nano-Scale Patterned Magnetic Tunnel Junction and Its Device Applications
Nano-scale patterned techniques, DCpulsed-current-driven magnetization switching and spin-dependent transport properties of magnetic tunnel junctions (MTJs) are presented in this paper. The experiments show that the spin transfer torque (STT) plays a main switching role in the magnetization current switching and the current-induced circular magnetic field plays an assisted-switching role in the...
متن کاملNanofabrication of Magnetic Tunnel Junction Pillars Targeting Nano-Oscillator Applications
Magnetic Tunnel Junctions are Spintronic devices constituted by two ferromagnetic layers separated by a nanometric insulating barrier. The theoretical predictions of giant Tunnel Magnetoresistance (TMR) values in fully crystalline Fe(001)/MgO(001)/Fe(001) structures [1] were soon followed by its experimental verification [2,3]. Such giant TMR effect arises from the conservation of the coherence...
متن کاملMagnetic tunnel junction sensors with pTesla sensitivity
Biomedical imaging techniques such as magneto-cardiography demand highly sensitive magnetic sensors capable to detect fields down to sub-picoTesla range at low frequencies (<10 hz). Currently, systems composed of superconducting quantum interference devices or hybrid supercond ucting/magnetoresistive (Mr) sensors fulfill such requirements, with the inconvenient of working at temperatures a few ...
متن کاملSecurity Protection for Magnetic Tunnel Junction
Energy efficiency is one of the most important parameters for designing and building a computing system nowadays. Introduction of new transistor and memory technologies to the integrated circuits design have brought hope for low energy very large scale integration (VLSI) circuit design. This excellency is pleasant if the computing system is secure and the energy is not wasted through execution ...
متن کاملGiant thermal spin-torque-assisted magnetic tunnel junction switching.
Spin-polarized charge currents induce magnetic tunnel junction (MTJ) switching by virtue of spin-transfer torque (STT). Recently, by taking advantage of the spin-dependent thermoelectric properties of magnetic materials, novel means of generating spin currents from temperature gradients, and their associated thermal-spin torques (TSTs), have been proposed, but so far these TSTs have not been la...
