Fig. 39: NFS on EuNi₂Ge₂ at room temperature as a function of pressure. EuF3 (left column) and EuS (right column) serve as reference samples. The observed modulations in the time spectra are due to the isomer shift between EuNi₂Ge₂ and the reference samples (see diagram below the spectra). The isomer shift in the diagram at bottom is given vs. EuF₃. 0.67 mm/s <=> ₀ = 4.8 · 10^-8 eV <=> 11.6 MHz.
