摘要：
In this paper various cation substituted Z-hexaferrites, prepared by the usual ceramic procedure and firing at a relatively low temperature (980 degreesC) in a 2 atm. oxygen pressure are discussed. On these materials extensive studies were undertaken, X-ray diffraction, IR absorption, scanning electronmicroscopy and a Mossbauer spectroscopy. Data obtained are explained, and discussed in details, leading to new information about the interaction of variant doped cation with the Z-hexaferrite Fe sites.
