The role of BaMnO_(3-δ) in the formation of YBaMn_2O_(6±δ)

摘要

There has been renewed interest in synthesizing and determining the physical properties of new manga-nese oxide-based materials and assessment of their potential exploitation. These range from compounds that show giant magnetoresistive properties such as is found in compounds based on LaMnO3 [1-3], to others formed from isostructural substitution of manganese for copper in some high temperature superconductors [4, 5].
