Abstract
The magnetic and dielectric properties of EuMn2O5 and BiMn2O5 crystals are investigated over a wide range of temperatures 4.2–250 K, including the range T≫T N ≃40 K. Significant departures from the Curie-Weiss law are observed in both crystals for the magnetic susceptibility in the paramagnetic range; they are attributed to the presence of correlated domains of magnetic order over a wide range of temperatures. Anomalies in the dielectric properties of the crystals are observed in the same temperature range T>T N and, as in the case T<T N , are correlated with the magnetic properties.
