The FUNMAH project
We are happy to announce a new publication in Applied Physics Letters: L. Straka, L. Fekete, and O. Heczko, Antiphase boundaries in bulk Ni-Mn-Ga Heusler alloy observed by magnetic force microscopy, Appl. Phys. Lett. 113 (2018) 172901; https://doi.org/10.1063/1.5052408 A
The project results related to the magnetic hysteresis and the effect of antiphase boundaries on the pinning of magnetic domains: L. Straka, L. Fekete, O. Heczko, Domain wall pinning in magnetic shape memory alloys with small and enlarged magnetic hysteresis
Our joint work with Material Physics Laboratory, Savonlinna, Finland: D. Musiienko, A. Saren, L. Straka, L. Klimša, K. Ullakko, High speed actuation of Ni-Mn-Ga micropillars by pulsed magnetic field, got Best Poster Award at Esomat Conference, Metz, France,
The project results related to our finding of nanotwinning in Ni-Mn-Ga were presented at Esomat International conference in Metz, France in oral and by poster (see below). We show that the material becomes nanotwinned for certain ranges of composition and
New project article has been published describing our finding of nanotwinning in Ni-Mn-Ga alloy. We show that the material becomes nanotwinned for certain ranges of composition and temperature. As the nanotwinning distorts the relation between the crystal lattice and the
The project results related to development of MSM microdevices and microactuators were presented at the ACTUATOR 2018: 16th International Conference on New Actuators, Bremen, Germany, 25–27 June 2018 orally and in the form of poster. They were also summarized in
Within the seminar organized at Institute of Physics I gave a presentation on my experience with MSCA-IF application process in order to help other applicants in their effort. The presentation included a workshop on application evaluation where I served as
In collaboration with Material Physics Laboratory of Lappeenranta University of Technology we started a series of experiments towards practical applications of magnetic shape memory alloys on microscale. This article summarizes the key result that focused Xe-ion beam milling can be
To encourage the research of magnetic shape memory alloys in Czech Republic, a seminar on magnetic shape memory alloys was organized in Ostre u Usteku on November 22-24, 2017. In beautiful landscape of Central Bohemian Highland, about 25 participants from
The oral talk “Magnetic shape memory alloys with magnetic hysteresis” was presented at ISPMA 14, the 14th INTERNATIONAL SYMPOSIUM ON PHYSICS OF MATERIALS (Prague, 10.9. – 15.9. 2017).
