Description
Moessbauer spectroscopy of samples of Ca2Fe2-xNbxO5+x with x values ranging from 0 to 0.8 and sintering temperatures of 1200degC and 1300degC shows the presence of two magnetic fields and a paramagnetic signal. The behaviour of the parameters as a function of x and of the sintering temperatures are discussed and compared with XRD results. (orig.)
