Study program: Advanced Materials
Theme: The preparation of soft magnetic composites by compaction
Supervisor: Prof. RNDr. Peter Kollár, CSc.
Consultant: RNDr. Ján Füzer, PhD.
Annotation: The study is oriented on investigation of the possibility of preparation of
the ferromagnetic based composite materials with inorganic or organic nonconductive
binder by uniaxial consolidation. The preparation process requires the knowledge
concerning ferromagnetic materials and compaction process, i.e. pressure,
temperature, atmosphere, duration of compaction. The aim is optimization of
compaction process of soft magnetic materials with required magnetic properties at
middle-frequency ac magnetic fields.

Theme: Study of structure and physical properties of amorphous and
nanocrystalline
alloys.
Supervisor: Prof. RNDr. Pavol Sovák, CSc.
Consultant: Dr. Vladimír Girman, PhD.
Annotation:Main purpose of the dissertation project is to handle technology of
production of amorphous and nanocrystalline alloys by rapid quenching. Due to
chemical composition and annealing treatment to optimize physical properties of
produced alloys. For structural characterization to use mainly electron microscopy
techniques.
