abstract By close analogy with multiferroic materials with coexisting long-range electric and magnetic orders a "multiglass" scenario of two different glassy states is observed in Sr(0.98)Mn(0.02)TiO(3) ceramics. Sr-site substituted Mn(2+) ions are at the origin of both a polar and a spin glass with glass temperatures T(g)approximate to 38 K and <= 34 K, respectively. The structural freezing triggers that of the spins, and both glassy systems show individual memory effects. Thanks to strong spin-phonon interaction within the incipient ferroelectric host crystal SrTiO(3), large higher order magnetoelectric coupling occurs between both glass systems.
