High-field magnetization studies and their analysis in RFe₁₁Ti and RFe₁₁TiH1 rare-earth intermetallics (an example: HoFe₁₁TiH_x, x = 0 and 1)

We present experimental high-field magnetization studies for the single-crystalline ferrimagnetic RFeTi compounds at example of holmium-based hydride in order to evaluate, compare and analyze the crystal-field and exchange parameters. We predict theoretically the magnetization behavior of HoFe₁₁Ti up to 80 T magnetic field for the first time. The results are compared with data for the parent compound HoFe₁₁TiH₁ and those with erbium and thulium (x = 0 and 1).
