High-field magnetic behavior and forced-ferromagnetic state in an ErFe₁₁TiH single crystal

The crystal-field and exchange parameters are determined for the single-crystalline hydride ErFe₁₁TiH compound by analyzing the experimental magnetization curves obtained in magnetic fields of up to 60 T. By using the calculated parameters we succeeded in modeling theoretical magnetization curves for ErFe₁₁TiH up to 200 Т and to study in detail the transition from ferrimagnetic to a ferromagnetic state in the appliedmagnetic field.
