Xavier Batlle is Full Professor in Condensed Matter Physics since 2010.  He is co-founder, co-leader and PI of the Group of Magnetic Nanomaterials of the University of Barcelona (UB) since 1993 (8 members at present and ca 40 in the past). He got his bachelor and Master Degrees in Physics in 1987 and his PhD in Physics in 1990, all from UB. He has been visiting researcher for about 4 years in a number of international laboratories, including Lawrence Berkeley National Lab (CA, USA), University of California San Diego (CA, USA), CNRS-Grenoble and Institute Laue Langevin (France), and University of Cambridge, among others. His work has aimed at the interplay among finite-size, surface, interface, interaction and proximity effects, and at the intimate correlation of the nanostructure (physical, chemical and magnetic) to the magnetic, electronic and electron transport properties of nanomaterials, including thin films and heterostructures, nanoparticles and nanostructures and ordered arrays of nanoelements. He is working on potential applications of magnetic nanoparticles in biomedicine and magnetic nanostructures in multi-state ultra-high density magnetic recording and multi-state logics. Lately, he started a new research in plasmonics.

Prof. Batlle holds 155 papers in journals of the Science Citation Index/Scopus, with ca 4,500/4700 citations (6,100 in Goggle Scholar) and a current h-index of 34 (h = 37 in Goggle Scholar). He is the first author of one of the seminal papers in the field of magnetic nanostructures and nanoparticles (Journal of Physics D: Applied Physics 35, R15 (2002)), which holds about 850 quotations in SCI (about 1,300 in Goggle Scholar). He has contributed to a number of scientific conferences (about 380), including about 100 invited talks and a continuous participation in International Scientific Committees. He has supervised 7 Ph. D Thesis (13 performed in the whole group), and he is currently supervising another one, and he has given 29 invited seminars throughout the world. He has devoted some efforts to the transfer of knowledge to privates companies since early 1990s. For example, the group has been involved in some projects for the use of magnetic nanoparticles in bioapplications and in another one related to applications in magnetic recording. Prof. Batlle is co-inventor of one international patent that has been licensed since 2007 and has generated about $159,000. The patent proposes the use of exchange bias in multi-state logics and magnetic recording, beyond binary logics.

He is Fellow of the American Physical Society (2012); Member of the Board of Directors of the Institute of Nanoscience and Nanotecnology of UB and area coordinator (Nanomagnetism and Spintronics);  Member of the Executive Committee of the Spanish Club of Magnetism; and Founder member of the Spanish Chapter of the Magnetics Society of the IEEE, for which he was President for 2012-2014. He was also member of the Executive Committee of the Solid State Physics Group of the Royal Spanish Physical Society until 2016. He acted as Chair of the Local Committee and Member of the Executive Committee of the International Conference of Magnetism ICM-2015 (Barcelona, Spain), with an attendance of 2,197 scientists. ICM is the largest international meeting on magnetism in the world.
