LABORATORI DE MAGNETISME, MICROONES I BAIXES TEMPERATURES (UBXLAB) Universitat de Barcelona.

--------The laboratory UBXLAB was founded initially at the beginning of the eighties by Professor Javier Tejada. The first works were performed using both Mössbauer spectroscopy and paramagnetic susceptibility measurements using a the Faraday force. In 1986 we did our first big efforts to modernize our equipments by buying a SQUID magnetometer which rwas helping us a lot in working in both magnetism (hexaferrites and single domain particles) and high temperature superconductors. In the nineties we move to lower temperatures (mK) and we also did big efforts in moving to the field of microwaves and their interactiuon with magentis systems. From those years 1989 to 1998 come our pionnering works and publications on the study of the tunneling of both the magnetic moment of single domain particles and the spin of molecular magnets. At the beginning of the new century we introduce the idea of the study molecular magnets when they are excited by microwaves and lately by surface acoustic waves. The aims during these years was the search of superradiance coming from the demagnetizing process of molecular magnets and the interaction of the electromagnetic radiation emitted by these nanomagnets with cavities and superconductors mirrors. In the case of the interaction of spins with surface acoustic waves our aim was to look for new quantum phenomena by performing high frequency magnetoacoustic experiments. We want also to mention our intense work during these years on different magnetic molecules and our objective to correlate their magnetic properties with their functionalization.

--------During all these years the group has published around 300 papers and got around 3.600 citations. The number of invited talks given in universities, research centers and international meetings is 120. During all these years we have participated in 25 research programs with the financial support of the catalan, spanish and european governments. Our main collaborators along these years have been groups from EEUU and different countries of Europe.

--------An important point to mention is our collaboration with different enterprises with the aim to generate intellectual property. The case is that during the last ten years we are inventors of 12 international patents being the owners those enterprises, spanish and international, with which we did collaborate. In that sense deserves to mention our intense and fruitful collaboration with Xerox Corporation.
