Study of LaCuAl3 structure by means of nuclear magnetic and quadrupole resonance
 Sgallová, Ráchel ; Chlan, Vojtěch (advisor) ; Englich, Jiří (referee)
In the presented bachelor thesis the structure of LaCuAl3 was studied on a series of metallic powder samples LaCuxAl4−x, x = 0,75; 0,9; 1 and 1,1 especially with respect to the local symetry of La atoms. 63 Cu, 65 Cu, 27 Al and 139 La nuclear magnetic resonance spectra were measured at room tempera- ture in external magnetic eld of 9,4 T. Some of the measured spectra were compared with simulated ones in order to access the number of nonequiva- lent atoms in the structure. Furthermore, the effect of Al/Cu stoichiometry on nuclear magnetic resonance spectra was observed and diccussed. 1
