Robert Maciaszek
Professional profile
Ing. Robert Maciaszek is a PhD student in Progressive Materials at the Pavol Jozef Šafárik University in Košice working under the supervision of Professor Peter Kollár. His main area of interest lies in the field of ferromagnetic materials. During his previous studies, he defended two theses related to them. “Spin waves in ferromagnets” was a theoretical investigation of the phenomenon of collective spin excitations in such types of materials. “Influence of mechanical and thermal processing on the properties of the iron-cobalt Fe50Co50 alloy” was a practical investigation into alloy properties depending on the conditions under which the samples used for measurements were created.
The working title of his PhD thesis is “Influence of surface treatment of ferromagnetic particles on magnetic properties of soft magnetically composite materials.” Its main goal is to develop a material whose particles will be almost identical in terms of shape, composition, and structure, and compare it to the other ones, where those parameters are all random, or partially ordered. During his research, he wants to investigate how the unification of the structure of Soft Magnetic Composite materials will affect their properties, and what additional opportunities will appear for them as a result.
Robert believes that a continuous improvement and creation of new Soft Magnetic Composite materials could affect the quality of future products and consequently the quality of life of the average person. Reducing costs and improving properties of materials is crucial for our future. Implementation of greener, more energy-saving solutions will allow the next generations for further developments.
