An international team led by Physics and Chemistry teams from the Faculty of Science and
Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose
Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that
atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) -
become magnetic. The article has been published in the February issue of the prestigious
international magazine in nanotechnology, Nanoletters (Vol.8, No. 2, 661-667 (2008)).
According to the research, in which researchers from the UPV/EHU as well as teams from
Australia and Japan have taken part, the magnetism appears reduce the dimensions of the
material to nanometric dimensions and surround it with previously selected organic molecules.
The magnetism of these nanoparticles is a permanent one (like iron) which, even at ambient
temperature, is quite significant. This amazing behaviour has been obtained not just with gold
(a phenomenon which had already been put forward as experimentally possible) but, in this
research, nanoparticles of silver and copper (the atoms of which are intrinsically
non-magnetic) with a size of 2 nm (0.000002 mm) have also been shown to be magnetic at
ambient temperature.

Gold and silver are also amazing conductors. I wonder how magnetising them would give them amazing electro-magnetism qualities.
