| Abstract: | The local structure of DyNiO3 nickelate at both sides of the insulator (T < T im) ? metal (T > T im) phase transition was studied by probe 57Fe Mössbauer spectroscopy. The character of change in the hyperfine parameters of probe iron atoms specifically near the phase-transition temperature (T ≈ T im) was analyzed. |
