It was shown that coexistent spin and dipole glass beahviours are strongly affected by the distribution of Mn ions between Sr and Ti sites. Two microscopical magnetoelectric coupling mechanisms, which can be involved in all magnetoelectric systems based on incipient ferroelectrics, were proposed. In the first one, the electric field modifies the spin susceptibility via spin-strain coupling of Mn4+. The second mechanism concerns Mn pairs coupled by the position-dependent exchange interaction.
