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…
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…
Single shot time-resolved magnetic x-ray absorption at a Free Electron Laser
Emmanuelle Jal, Mikako Makita, Benedikt Rösner +18
Ultrafast dynamics are generally investigated using stroboscopic pump-probe measurements, which characterize the sample properties for a single, specific time delay. These measurem…
Direct observation of enhanced magnetism in individual size- and shape-selected 3d transition metal nanoparticles
Armin Kleibert, Ana Balan, Rocio Yanes +10
Magnetic nanoparticles are important building blocks for future technologies ranging from nano-medicine to spintronics. Many related applications require nanoparticles with tailore…
Domain-resolved room-temperature magneto-electric coupling in manganite-titanate heterostructures
Rajesh Vilas Chopdekar, Michele Buzzi, Catherine Ann Jenkins +3
We present a model artificial multiferroic system consisting of a (011)-oriented ferroelectric Pb(Mg,Nb,Ti)O substrate intimately coupled to a ferromagnetic (La,Sr)MnO film…
