Anizotropic magnetic properties of the tetragonal R2TIn8 compounds
 Pajskr, Karel ; Javorský, Pavel (advisor) ; Svoboda, Pavel (referee)
This thesis deals with termodynamic and magnetic properities of the intermetalic compound Er2RhIn8. This compound is a member of the wide intermetalics family of RX3, RTX5 and R2TX8, crystallizing in related structures and having non-trivial magnetic properities and phase diagrams, including the Ce-based heavy-fermion superconductivity. The thesis is a part of the broader research of these compounds. Single Er2RhIn8 crystals were prepared from flux with their stoichiometry and structure verified by energy-dispersive X-ray spectrometry and Laue method, respectively. Heat capacity and magnetization measurements were performed on the produced crystals and the measured data were analyzed. As a result, the compound was classified as antiferromagnetic under the order temperature of 3,8(1) K with an easy magnetization axis of [110] and relatively low magnetocrystalline anisotropy. Heat capacity measurements indicate a relatively small splitting of the energy levels of the rare-earth ion ground state due to the crystal field.
