Fernando Luis
Fernando Luis received his Ph.D. from the University of Zaragoza, Spain, in 1997, with a thesis on the phenomenon of spin quantum tunneling. He performed his post-doctoral research work first at the Kamerlingh Onnes Laboratory of the University of Leiden, The Netherlands, between 1998 and 2000, and then at the Institute of Materials Science of Aragón (ICMA), Spain, from 2000 until 2003. Since 2003, he has held a permanent appointment with the Spanish Council of Research (CSIC) at the ICMA. His research activity focuses mainly on the study of magnetic nanoparticles and molecular clusters, with a special interest on phenomena, like quantum tunneling, quantum coherence, dipolar magnetism, and quantum phase transitions, which occur near the absolute zero.
Reversal of expectations
A microscopic study of magnetic nanoislands on a surface challenges the widely held view that all atoms in a relaxing nanoparticle flip their spins in unison. Read More »
