Topotactic synthesis, structure and magnetic properties of a new hexagonal polytype of silver cobaltate(III) AgCoO2+δ
Hervé Muguerra, Claire Colin, Michel Anne +2
A new form of delafossite-type AgCoO2+δwas prepared using ion exchange from Na0.75CoO2 in molten AgNO3-NH4NO3 at 175 degrees C. Its structure was determined by Rietveld refinement…
High domain wall velocity at zero magnetic field induced by low current densities in spin-valve nanostripes
Stefania Pizzini, Vojtech Uhlir, Jan Vogel +14
Current-induced magnetic domain wall motion at zero magnetic field is observed in the permalloy layer of a spin-valve-based nanostripe using photoemission electron microscopy. The…
Diamond nanoparticles as photoluminescent nanoprobes for biology and near-field optics
A. Cuche, Y. Sonnefraud, O. Faklaris +6
We present results showing the potential of diamond nanoparticles with size less than 50 nm as photoluminescent nanoprobes for serving as stable point-like emitters attached at the…
Magnetocaloric properties of Fe_{2-x}T_xP (T = Ru and Rh) from electronic structure calculations and magnetisation measurements
B. Wiendlocha, J. Tobola, S. Kaprzyk +3
An analysis of the magnetocaloric properties of the pure and substituted Fe2P compounds is made based on KKR-CPA electronic structure calculations and magnetisation M(H,T) measurem…
Fluorescent oxide nanoparticles adapted to active tips for near-field optics
A. Cuche, B. Masenelli, G. Ledoux +5
We present a new kind of fluorescent oxide nanoparticles with properties well suited to active-tip based near-field optics. These particles with an average diameter in the range 5-…
Ab initio GW many-body effects in graphene
P. E. Trevisanutto, C. Giorgetti, L. Reining +2
We present an {\it ab initio} many-body GW calculation of the self-energy, the quasiparticle band plot and the spectral functions in free-standing undoped graphene. With respect to…
