| Abstract: | We have carried out a study of the ionic conductivity of NaMgF3, KMgF3 and KZnF3 up to temperatures close to the melting point. Our results, in contrast to previous reports in the literature, show no abnormal ionic conductivity at high temperatures. Care in interpretation of results is required because of surface electronic conduction. |
