摘要

The work is devoted to the study of the magnetic DC and AC susceptibilities, as well as to the analysis of spin dynamics (relaxation processes) of yttrium- and bismuth-doped rare earth holmium titanates. An influence of doping degree and the type of dopant on the magnetic properties of holmium titanates have been evaluated. The magnetization curves were measured. The measurement of frequency dependence of the AC susceptibility allowed us to analyze spin dynamics and estimate characteristic magnetic relaxation times in the studied systems.
