- Аннотация: Off-stoichiometric (La0:6Sr0:35)(MnTi0:05) MnO3 manganite was studied with in-phase (real, χ 0) and out-of-phase (imaginary, χ 00) components of ac susceptibility measurements. Short- and long-time relaxation effects, manifested by the revealed negative χ 00, were observed. The effects are explained at the frame of Landau theory of phase transitions where a coexistence of stable and metastable states is considered. It is supposed that the appearance of negative χ 00 is an intrinsic feature of magnetic materials with impurities, defects and vacancies blocking nucleation and growth of new phase.
