Mössbauer study of Na${}_{0.82}$CoO${}_2$ (doped by 1% ${}^{57}$Fe)

M. Pissas, V. Psycharis, D. Stamopoulos +3

We studied by Mössbauer spectroscopy the Na${}_{0.82}$CoO${}_2$ compound using 1% ${}^{57}$Fe as a local probe which substitutes for the Co ions. Mössbauer spectra at T=300 K revealed tw…
