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…
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…
Spin configurations in Co2FeAl0.4Si0.6 Heusler alloy thin film elements
C. A. F. Vaz, J. Rhensius, J. Heidler +11
We determine experimentally the spin structure of half-metallic Co2FeAl0.4Si0.6 Heusler alloy elements using magnetic microscopy. Following magnetic saturation, the dominant magnet…
Element-resolved x-ray ferrimagnetic and ferromagnetic resonance spectroscopy
G. Boero, S. Mouaziz, S. Rusponi +4
We report on the measurement of element-specific magnetic resonance spectra at gigahertz frequencies using x-ray magnetic circular dichroism (XMCD). We investigate the ferrimagneti…
Paramagnetism of the Co sublattice in ferromagnetic ZnCoO films
A. Barla, G. Schmerber, E. Beaurepaire +11
Using the spectroscopies based upon x-ray absorption, we have studied the structural and magnetic properties of ZnCoO films ( = 0.1 and 0.25) produced by reactive…
