Abstract:
Short time relaxation effect in Nd0.5Sr0.5MnO 3 manganites was observed. The effect is
manifested as negative peak of imaginary component of ac magnetic susceptibility near the point of first
order phase transition. The effect is explained at the frame of Landau theory of phase transition, where the
coexistence of metastable and stable phases is considered. ?? 2008 IEEE.
