Title: Long-Time Variation of Magnetic Structure in (Pr xLa 1-x)Co 2Si 2: Coexistence of Slow and Fast Processes in Magnetic Phase Transition

In this paper, long-time variations of the magnetic structure in PrCo 2Si 2 and (Pr 0.98La 0.02)Co 2Si 2 were studied by magnetization and time-resolved neutron scattering measurements. The amplitudes of magnetic Bragg peaks showed marked time variations after cooling or heating across the magnetic transition temperature T 1 between two different antiferromagnetic phases. However, the amplitude of the time variation decreased rapidly with increasing distance from T 1. Finally, we analyzed the results on the basis of a phase transition model that includes the coexistence of fast and slow processes.
