13. Brief summary of academic career:

Prof. Batlle has contributed to the fundamental understanding of the magnetic properties of nanomaterials, including magnetic nanoparticles and ordered arrays of nanoelements, heterogeneous alloys and granular metals, and exchange coupled antiferromagnetic /ferromagnetic thin film bilayers and core/shell nanoparticles. 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 and electron transport properties. He has also contributed to the fundamental understanding of the giant magnetocaloric effect in intermetallic alloys by studying the entropy change and the latent heat under magnetic field in materials showing first-order magneto-structural phase transitions arising from magneto-elastic coupling.

He founded in 1993, in collaboration with Prof. Labarta, The Group of Magnetic Nanomaterials, which is one of the research centres in Spain in the field of magnetic and transport properties at the nanoscale, both from experimental and numerical simulation points of view. Recently, he wrote an invited review paper for the Royal Spanish Physical Society about the status of Magnetism in Spain, which was published in the journal of the Society in 2009 (Revista de Física, vol 23, pag. 23-29). The Group has also got an international reputation in the field of magnetism at the nanoscale.

He holds about 155 papers in high-impact journals of the Science Citation Index, with ca 4,200 citations (5,600 in Goggle Scholar) and a current h-index of 34 (h = 35 in Goggle Scholar). He is the first author of one of the seminal papers in the field of magnetic nanostructures (Journal of Physics D: Applied Physics 35, R15 (2002)), which holds about 800 quotations (about 1,200 in Goggle Scholar). Besides, his paper (corresponding author) P. Guardia et al., Journal of Magnetism and Magnetic Materials 316 (2), e756 (2007), was the 9th most cited paper published within the period 2007-2012 in the Journal (ca 240 quotations in 11/2017). He has co-authored the Opening paper of the new Critical Issues Section in the JMMM .He has also contributed to a number of scientific conferences (about 370), including more than 100 invited talks and a continuous participation in International Scientific Committees.

He has also devoted some efforts to the transfer of knowledge to privates companies since early 1990s. For example, the group was involved in a project for the use of magnetic nanoparticles in bioapplications and in another related to applications in magnetic recording. Prof. Batlle is also co-inventor of one international patent that has been licensed since 2006 and has generated about $159,000. The patent proposes the use of exchange bias in multi-state logics and magnetic recording, beyond binary logics.

Finally, he is Full Professor in Condensed Matter Physics, Fellow of the American Physical Society, elected member of the Board of Directors and past Area Coordinator of the Institute of Nanoscience and Nanotecnology of the University of Barcelona, past elected member of the Scientific and Executive Committees of the Solid State Physics Group of the Royal Spanish Physical Society, elected 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 and also Past-President (2014-2016), and 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. scientists. ICM is the largest international meeting on magnetism in the world.
