Room-temperature ferromagnetism in the mixtures of the TiO2 and Co3O4 powders
A. Serrano, E. Fernandez Pinel, A. Quesada +10
We report here the observation of ferromagnetism (FM) at 300 K in mixtures of TiO2 and Co3O4 powders despite the antiferromagnetic and diamagnetic character of both oxides respecti…
Negative nonlocal resistance in mesoscopic gold Hall bars: Absence of giant spin Hall effect
G. Mihajlovic, J. E. Pearson, M. A. Garcia +2
We report the observation of negative nonlocal resistances in multiterminal mesoscopic gold Hall bar structures whose characteristic dimensions are larger than the electron mean-fr…
Sources of experimental errors in the observation of nanoscale magnetism
M. A. Garcia, E. Fernandez Pinel, J de la Venta +6
It has been recently reported that some non-magnetic materials in bulk state, exhibit magnetic behavior at the nanscale due to surface and size effects. The experimental observatio…
Palladium: A localised paramagnetism
A. Hernando, B. Sampedro, M. A. Garcia +4
We report on the origin of ferromagnetic like behaviour observed for 2.4 nm size Pd nanoparticles. Localised magnetic moments on metallic surfaces have been recently shown to induc…
Giant magnetic anisotropy at nanoscale: overcoming the superparamagnetic limit
A. Hernando, P. Crespo, M. A. Garcia +3
It has been recently observed for palladium and gold nanoparticles, that the magnetic moment at constant applied field does not change with temperature over the range comprised bet…
