The conditions of field and voltage for inducing steady state excitations in fully perpendicular magnetic tunnel junctions (pMTJs), adapted for memory applications, were numerically investigated by the resolution of the Landau-Lifshitz-Gilbert equation in the macrospin approach. Both damping-like and the field-like spin transfer torque terms were taken into account in the simulations, as well as the contribution of the second order uniaxial anisotropy term (K2), which has been recently revealed…

Stability phase diagram of a perpendicular magnetic tunnel junction in noncollinear geometry

Experimental measurements performed on MgO-based perpendicular magnetic tunnel junctions show a strong dependence of the stability voltage-field diagrams as a function of the direction of the

Phase diagrams of MgO magnetic tunnel junctions including the perpendicular spin-transfer torque in different geometries

We calculate the switching voltages for MgO-based magnetic tunnel junctions taking into account both the in-plane and the fieldlike spin-torque terms. To this end, we analytically solve the

Second order anisotropy contribution in perpendicular magnetic tunnel junctions

It is found that a second-order anisotropy term of the form −K2cos4θ must be added to the conventional uniaxial –K1cos2θ term to explain the experimental data, and this higher order contribution exists both in the free and reference layers.

Voltage-induced magnetization dynamics in CoFeB/MgO/CoFeB magnetic tunnel junctions

The numerical simulations involving the micromagnetic method based on the Landau-Lifshitz-Gilbert equation of motion indicate that the magnetization motion in both layers is induced by a combination of VCMA and transferred angular momentum, even though the magnetic easy axes of the two layers are different.

Consequences of an interface-concentrated perpendicular magnetic anisotropy in ultrathin CoFeB films used in magnetic tunnel junctions

We examine the consequences of a strongly interface-concentrated perpendicular magnetic anisotropy (PMA) energy in CoFeB thin films currently in wide use in magnetic tunnel junctions (MTJs) for

Macrospin description of the perpendicular polarizer-planar free-layer spin-torque oscillator

For the ``perpendicular polarizer-planar free layer'' spin torque oscillator a complete current-field state diagram in the macrospin description is presented. This diagram is quite different from one

A perpendicular-anisotropy CoFeB-MgO magnetic tunnel junction.

Inter interfacial perpendicular anisotropy between the ferromagnetic electrodes and the tunnel barrier of the MTJ is used by employing the material combination of CoFeB-MgO, a system widely adopted to produce a giant tunnel magnetoresistance ratio in MTJs with in-plane an isotropy.

Influence of MgO barrier quality on spin-transfer torque in magnetic tunnel junctions

We studied the bias dependence of spin transfer torque in the MgO-based magnetic tunnel junction using a field-modulated spin torque ferromagnetic resonance measurement technique for three devices

Measurement of the spin-transfer-torque vector in magnetic tunnel junctions

The transfer of spin angular momentum from a spin-polarized current to a ferromagnet can generate sufficient torque to reorient the magnet’s moment. This torque could enable the development of

Saturation of VCMA in out-of-plane magnetized CoFeB/MgO/CoFeB magnetic tunnel junctions

Voltage controlled magnetic anisotropy (VCMA) currently attracts considerable attention as a novel method to control and manipulate magnetic moments in high-speed and low-power spintronic
