Soft X-ray spectro-ptychography on boron nitride nanotubes, carbon nanotubes and permalloy nanorods
Jaianth Vijayakumar, Hao Yuan, Nicolas Mille +6
Spectro-ptychography offers improved spatial resolution and additional phase spectral information relative to that provided by scanning transmission X-ray microscopes (STXM). Howev…
Absence of a pressure gap and atomistic mechanism of the oxidation of pure Co nanoparticles
Jaianth Vijayakumar, Tatiana M. Savchenko, David M. Bracher +7
We present a detailed atomistic picture of the oxidation mechanism of Co nanoparticles and its impact on magnetism by experimentally following the evolution of the structure, chemi…
Electric field control of magnetism in Si3N4 gated Pt/Co/Pt heterostructures
Jaianth Vijayakumar, David Bracher, Tatiana M. Savchenko +3
In this work we show the presence of a magnetoelectric coupling in silicon-nitride gated Pt/Co/Pt heterostructures using X-ray photoemission electron microscopy (XPEEM). We observe…
Magnetic properties and domain structure of ultrathin yttrium iron garnet/Pt bilayers
Johannes Mendil, Morgan Trassin, Qingqing Bu +10
We report on the structure, magnetization, magnetic anisotropy, and domain morphology of ultrathin yttrium iron garnet (YIG)/Pt films with thickness ranging from 3 to 90 nm. We fin…
Engineering Relaxation Pathways in Building Blocks of Artificial Spin Ice for Computation
Hanu Arava, Naemi Leo, Dominik Schildknecht +5
Nanomagnetic logic, which makes use of arrays of dipolar-coupled single domain nanomagnets for computation, holds promise as a low power alternative to traditional computation with…
