Abstract :

Short time relaxation effect in Nd_0.5Sr_0.5MnO₃ 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.
