The mechanical back-action of a spin-wave resonance in a magnetoelastic thin film on a surface acoustic wave
Praveen G. Gowtham, Dominic Labanowski, Sayeef Salahuddin
Surface acoustic waves (SAWs) traveling on the surface of a piezoelectric crystal can, through the magnetoelastic interaction, excite traveling spin-wave resonance in a magnetic fi…
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…
A Critical Analysis of the Feasibility of Pure Strain-Actuated Giant Magnetostrictive Nanoscale Memories
Praveen G. Gowtham, Graham E. Rowlands, Robert A. Buhrman
Concepts for memories based on the manipulation of giant magnetostrictive nanomagnets by stress pulses have garnered recent attention due to their potential for ultra-low energy op…
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…
Central role of domain wall depinning for perpendicular magnetization switching driven by spin torque from the spin Hall effect
O. J. Lee, L. Q. Liu, C. F. Pai +4
We study deterministic magnetic reversal of a perpendicularly magnetized Co layer in a Co/MgO/Ta nano-square driven by spin Hall torque from an in-plane current flowing in an under…
Ultrafast switching of a nanomagnet by a combined out-of-plane and in-plane polarized spin-current pulse
O. J. Lee, V. S. Pribiag, P. M. Braganca +3
We report on spin valve devices that incorporate both an out-of-plane polarizer (OPP) to quickly excite spin torque (ST) switching and an in-plane polarizer/analyzer (IPP). For pul…
