Crystal-Field and Exchange Parameters Obtained from the High-Field Magnetization of ErFe11Ti: Revisited

Abstract

We perform a high-field magnetization study for the single-crystalline ferrimagnetic ErFe11Ti compound in order to redefine the crystal-field and exchange parameters. For the first time, we predict theoretically the magnetization behavior of ErFe11Ti up to 100 T magnetic field.

The latter allows us to observe the full magnetization process (up to the forced-ferromagnetic state) in ErFe11Ti. The results are compared with data for the hydride ErFe11TiH1.
