Abstract

Magnetic relaxation measurements in constant fields (H2 = 10, 100, 156, 200 and 233 Oe) in the temperature range between 1.8 and 16 K have been recorded. Our results show that the low-temperature magnetic viscosity has a non-thermal contribution that depends on the value of the applied magnetic field. The most plausible explanation for this non-thermal viscosity is the occurrence of single-domain tunneling in grains.
