| heal.abstract | In exchange-coupled ferromagnetic/antiferromagnetic La0.60Ca0.40MnO3(FM)/La0.33Ca0.67MnO3(AF) multilayers the magnetization reversal mechanism is probed by magnetic viscosity and remanence measurements below (5 K) and above (80 K) the blocking temperature T-B=70 K. The magnetic relaxation follows the ln(t) behavior at 5 K, which is a universal feature of a slow relaxation process, whereas at 80 K the time decay requires an additional exponential term. Below T-B, the observed loop asymmetries in the irreversible susceptibility (chi(irr)) and the magnetic viscosity (S) reveal two inequivalent reversal mechanisms between the field increasing and field decreasing branches of the hysteresis loop. | en |
