Project researchers Petr Veřtát and Michal Rameš participated at the 11th Student Scientific Conference on Solid State Physics and Materials, 12-15th of September 2022. The goal of the conference is to provide students with the opportunity to present their contributions in a wider, open forum, to develop professional communication skills, to expand their professional outlook on topics presented by other conference participants, to refine their opinions in informal discussions and to establish a number of new personal and professional relationships.
Ph.D. student Petr Veřtát presented his lecture “Superspace symmetry of Ni-Mn-Ga-based crystals“:
(see also figure above)
Abstract: The discovery of aperiodic crystals (crystals where three-dimensional lattice periodicity is absent) initiated crystallographers’ journey into higher dimensions. Using (3+1)-dimensional superspace, we introduce the world of incommensurate martensite structures with one-dimensional modulation and show how to deal with the lack of translational symmetry.
Ph.D. student Michal Rameš presented his lecture “Magnetocrystalline anisotropy of Ni-Mn-Ga-Co-Cu martensite“:
Abstract: Large magnetocrystalline anisotropy (MCA) is a prerequisite for most of the functionalities of magnetic shape memory alloys, particularly the large, up to 12% magnetic field-induced strain. In the presentation the methods of MCA determinations are summarised, and selected measurements on Ni-Mn-Ga-Co-Cu are discussed together with the theoretical origin of the magnetocrystalline anisotropy and its evolution with dopand concentration.
