The project is aimed at the investigation of magnetic frustration effects in transition-metal (TM) and rare-earth (RE) spinels. The TM AB2X4 (A= Fe, Mn; B= Sc, Y; X= S, Se) family is interesting due to the realization of spiral spin- and spin-orbital liquid states. We plan to extend available experimental findings on polycrystalline samples by growing and investigating single crystals. The potential of the RE AB2X4 (A=Cd, Zn; B=Er, Yb; X =S, Se) compounds is at the beginning of its exploration. The first experiments performed on polycrystalline CdEr2Se4 suggest it is the first spin ice outside the rare-earth pyrochlore series. We will grow single crystals of several members of the RE family and investigate them using advanced local-probe and scattering techniques.
