Academic Centre for Materials and Nanotechnology invites for a seminary that will be held on 16th November, 2017, at 14.00 (2.00 pm).
A lecture titled Impact of hydrogen absorption on crystal structure and magnetic properties will be given by PhD Silvie Mašková from Department of Condensed Matter Physics, Charles Universityin in Prague, Czech Republic.
Venue: Kawiory 30 Street, building D-16, auditorium room 1.02A
Abstract of the lecture
The sensitivity of the interactions in the intermetallic systems to modification of the crystal structure makes the experimental techniques involving alternation of the atomic arrangement especially important. Various studies under compression are well-known examples of such methods. From this point of view hydrogenation can be treated as a complementary technique that provides „negative“ pressure. The hydrides can be defined as compounds for which the hydrogen absorption leads to the modifications of the crystal structure, such as pure lattice expansion or the formation of a new structure. As a result, the new compounds (hydrides) exhibit qualitatively new physical properties and such modifications provide us with additional information on the peculiarities of interatomic interactions in the initial compounds.
