This paper concerns the synthesis of yttrium-dilute Tb0.27-xYxDy0.73Fe2 intermetallic series with a borderline compound Tb0.27Dy0.73Fe2 known as Terfenol-D by arc melting, XRD analysis and 57Fe Mössbauer effect studies at 295 K. XRD analysis (295 K) shows that all samples crystallize in a cubic, Fd3m, MgCu2-type structure. The lattice parameter increases along with yttrium content. Mössbauer effect spectra for the Tb0.27-xYxDy0.73Fe2 series collected at 295 K consist of two subspectra due to easy direction of magnetization <111>. Hyperfine interaction parameters: isomer shift, magnetic hyperfine field and a quadrupole splitting were obtained from the fitting procedure of the spectra.
