Thickness-Dependent Magnetoelasticity and its Effects on Perpendicular Magnetic Anisotropy in Ta|CoFeB|MgO Thin Films
Praveen G. Gowtham, Gregory M. Stiehl, Daniel C. Ralph +1
We report measurements of the in-plane magnetoelastic coupling in ultra-thin Ta|CoFeB|MgO layers as a function of uniaxial strain, conducted using a four-point bending apparatus. F…
Traveling surface spin-wave resonance spectroscopy using surface acoustic waves
Praveen G. Gowtham, Takahiro Moriyama, Daniel C. Ralph +1
Coherent gigahertz-frequency surface acoustic waves (SAWs) traveling on the surface of a piezoelectric crystal can, via the magnetoelastic interaction, resonantly excite traveling…
Enhancement of the Anti-Damping Spin Torque Efficacy of Platinum by Interface Modification
Minh-Hai Nguyen, Chi-Feng Pai, Kayla X. Nguyen +3
We report a strong enhancement of the efficacy of the spin Hall effect (SHE) of Pt for exerting anti-damping spin torque on an adjacent ferromagnetic layer by the insertion of $\ap…
