László Bottyán has been member of the Institute('s predecessor) since 1985 and head of the Nuclear Solid State Physics Laboratory (now Functional Nanostructures Research Group) since 1995. His present interest is application of nuclear methods (as well as neutron and synchrotron radiation) in solid state physics and material science especially in low-dimensional magnetic systems, such as thin multilayered films and nanostructures including phenomena like interdiffusion, finite size effects as well as superconductor/ferromagnet, ferromagnet/ferromagnet proximity and exchange bias effects.
He is coauthor of more than 90 research publications which received above 800 citations (as of January 2018).
He is beam line responsible of the GINA neutron reflectometer at the Budapest Neutron Centre.
