Abstract
The compound YBa4Fe3Oy was synthesized where the Fe atoms completely s ubstituted for the Cu atoms in YBa4Fe3Oy. The X-ray phase analysis of the synthesized material showed that the diffraction pattern correspon ds to the data for the compound YBa(4)Fe3O(y). Fe-57 Mossbauer measure ments of the compound were performed at room temperature after differe nt heat treatments: high-temperature synthesis in an oxygen atmosphere and in air, and low-temperature annealing in oxygen and in vacuum. No magnetic components are observed after any heat treatments. The Fe at oms in the compound have two valence states, Fe3+ and Fe4+. The ideali zed model of the 1-4-3 Fe structure is discussed.
