A kutatási téma leírása:

Our research group has been engaged for the last two decades in the electrochemical preparation and experimental study of metallic magnetic/non-magnetic multilayer films which exhibit the phanomenon of giant-magnetoresistance (GMR) based on spin-dependent electron transport in ferromagnets. The electrochemical technique provides a unique opportunity to electrodeposit materials into the nanoscale pores of some special non-metallic membranes and this offers the possibility to fabricate nanowires with a diamter of typically 100 nm. Similarly to the preparation of mulitlyer films, the electrochemical deposition method enables the modulation of the chemical composition also along the nanowire length and in such multilayered nanowires the GMR effect can also be observed. By specific element combinations, one can achieve various specific properties of such nanowires (e.g., magnetically hard and soft materials, magnetic metals and semimetals or superconductors). The PhD work includes the electrochemcial preparation of nanowires, their structural characterization by electronmicroscopy and X-ray diffraction, as well as studying their magnetic and transport properties. The research will be caried in collaboration with a group in Dresden, Germany with the topic focusing on the fabrication of magnonic crystals by electrochemical routes.
