The hyperfine magnetic field (H-hf) in 0.2 at.% Hf-Ni alloy is measured at the Ta-181 probe using the time-differential perturbed angular correlation (TDPAC) method, in the temperature range 78-675 K. The obtained value of 8.6 (3) T at room temperature is in good agreement with the previously reported measurements for similar Hf concentrations in Ni. X-ray powder diffraction (XRPD) experiments confirmed that small atomic concentrations of Hf atoms ( LT 1 at.%) mainly substitute on Ni lattice sites in the fee crystal lattice without forming any intermetallic phase. In addition, ab-initio calculation using all-electron augmented plane waves plus local orbitals (APW + lo) formalism is performed and the obtained result for the hyperfine magnetic field at Ta site is in accordance with the measurement.
