Abstract : The structure and decomposition of wustite (Fe(1-x)O) have been studied by Mossbauer, magnetic and X-ray techniques. The antiferromagnetic Curie temperature of hematite (alpha-Fe2O3) has been determined to be about 685C from Mossbauer measurements. The Mossbauer efficiency of krypton in a clath-rate compound is constant at about 20% in the range 150-300K, and increases rapidly at lower temperatures. This behavior is not consistent with any static potential. (Author)
