A Magnetic and Mössbauer Spectral Study of PrFe₁₁Ti and PrFe₁₁TiH
The lattice parameters, magnetic and Mössbauer spectral properties of PrFe11Ti and PrFe11TiH have been measured between 4.2 and 295K. Both compounds crystallize in the ThMn12-type structure. The insertion of hydrogen in PrFe11Ti anisotropically expands the unit-cell volume by 0.4%. Both compounds are ferromagnetically ordered with Curie temperatures of 547 and 604K, respectively. Between 4.2 and 295K, the easy magnetization direction is within the basal plane along the  direction as indicated by the Mössbauer spectra which have been fit with a model taking into account both the binomial distribution of titanium near neighbors of the iron atoms and the basal orientation of the magnetic moments.
