Sažetak
Magnetic relaxation measurements at different temperatures below the blocking temperature were performed on Mn12-acetat in fields corresponding to the first (zero) resonance. Three temperature regimes could be identified: Below 2.0K (2.3K) a square root time dependence is present, indicating thermally assisted tunneling. Up to 2.1K (2.6K) pure exponential behaviour is found, typical for thermally activated tunneling. Just below T_B a new regime with strongly non exponential behaviour could be identified.
