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…
Single femtosecond laser pulse excitation of individual cobalt nanoparticles
Tatiana M. Savchenko, Michele Buzzi, Ludovic Howald +12
Laser-induced manipulation of magnetism at the nanoscale is a rapidly growing research topic with potential for applications in spintronics. In this work, we address the role of th…
Electronic phase separation at LaAlO3/SrTiO3 interfaces tunable by oxygen deficiency
V. N. Strocov, A. Chikina, M. Caputo +7
Electronic phase separation is crucial for the fascinating macroscopic properties of the LaAlO3/SrTiO3 (LAO/STO) paradigm oxide interface, including the coexistence of superconduct…
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…
Thick Permalloy films for the imaging of spin texture dynamics in perpendicularly magnetized systems
Simone Finizio, Sebastian Wintz, David Bracher +9
We demonstrated that thick Permalloy films exhibiting a weak growth-induced perpendicular magnetic anisotropy can be employed as an ideal test system for the investigation of gyrat…
