Aging, rejuvenation and memory effects in re-entrant ferromagnets
V. Dupuis, E. Vincent, M. Alba +1
We have studied the slow dynamics of the ferromagnetic phases of the re-entrant CdCr_{2x}In_{2-2x}S_4 system for 0.85<x<=1 by means of low frequency ac susceptibility and magnetiza…

Finite Size Effects on Spin Glass Dynamics
Y. G. Joh, R. Orbach, G. G. Wood +2
The recent identification of a time and temperature dependent spin glass correlation length, , has consequences for samples of finite size. Qualitative arguments are gi…
