The magnetic properties of the ferromagnetic compounds, SmFe11Ti and SmFe11TiH1−δ, which are potential candidates for high performance permanent magnets are investigated. At room temperature both compounds exhibit a uniaxial anisotropy, with the easy direction of magnetization parallel to the tetragonal axis. High field magnetization measurements up to 240 kOe in continuous fields are reported. The major changes upon hydrogen insertion are increases of the Curie temperature and of the saturation magnetization. The magnetic anisotropy constants, K1 and K2, are determined and the insertion of hydrogen is found to increase K1. If the external field is applied perpendicular to the alignment direction, anomalous magnetization behaviors are observed in both compounds below about 150 K. The shape of this anomaly is strongly modified by the hydrogen insertion. © 1996 American Institute of Physics.
