摘要：

Variable-temperature Co-K-EXAFS measurements establish the occurrence of two cobalt sites, probably associated with the two spin states, above 400K. The population of the two Co sites becomes equal around 670 K, at which temperature the change in space group occurs. © 1993 Academic Press, Inc.
