Abstract
Mössbauer measurements on YbFeCuO4 were performed in the temperature range 300-13 K. The compound was found to be paramagnetic at 300 K and magnetically ordered at 13 K. The parameters obtained from the fit of the experimental data showed that the trivalent charge state of iron is present and occupy more than one site. It also confirmed that Fe2+ was replaced by Cu2+. The intermediate temperature measurements on YbFeCuO4 indicated that the transition temperature is below 220 K.
