 Abstract: Perovskite oxides ABO(3) offer a vast playground for applications and basic research. Especially multifunctionality is a frequently targeted aim, since the replacement of the A and/or B sublattice ions easily changes the properties of the system. Here we concentrate on the perovskite EuTiO3 (ETO) which was ignored by the scientific community for a long time. We review recent results on it and show that this compound provides many surprises which may offer novel device techniques and applications. In particular we demonstrate that far above its Neel temperature T-N = 5.7 K magnetism exists and new magneto-dielectric-elastic coupling is at work. From capacitance and muon spin rotation (mu SR) data we conclude that the phase diagram of ETO is much more complex than believed and a variety of new phases are described. (c) 2017 Elsevier B.V.
