Temperature dependence of microwave voltage emission associated to spin-transfer induced vortex oscillation in magnetic tunnel junction
P. Bortolotti, A. Dussaux, J. Grollier +7
The temperature dependence of a vortex-based nano-oscillator induced by spin transfer torque (STVO) in magnetic tunnel junctions (MTJ) is considered. We obtain emitted signals with…
Sub-Poissonian shot noise in CoFeB/MgO/CoFeB-based magnetic tunneling junctions
Tomonori Arakawa, Koji Sekiguchi, Shuji Nakamura +7
We measured the shot noise in the CoFeB/MgO/CoFeB-based magnetic tunneling junctions with a high tunneling magnetoresistance ratio (over 200% at 3 K). Although the Fano factor in t…
Spin-Torque Diode Measurements of MgO-Based Magnetic Tunnel Junctions with Asymmetric Electrodes
R. Matsumoto, A. Chanthbouala, J. Grollier +8
We present a detailed study of the spin-torque diode effect in CoFeB/MgO/CoFe/NiFe magnetic tunnel junctions. From the evolution of the resonance frequency with magnetic field at d…
Vertical current induced domain wall motion in MgO-based magnetic tunnel junction with low current densities
A. Chanthbouala, R. Matsumoto, J. Grollier +11
Shifting electrically a magnetic domain wall (DW) by the spin transfer mechanism is one of the future ways foreseen for the switching of spintronic memories or registers. The class…
