Abstract (english)
The dependence of the magnetic moment m on the temperature T and the magnetic field H in a synthesized molecular magnet Mn_12-acetate has been measured using a SQUID magnetometer. The splitting of zero-field cooled (ZFC) and field-cooled (FC) m(T) curves below the so-called blocking temperature TB ( ≈ 3.6 K at H = 0) was observed. By measuring the time relaxation of m, it was found that it tended to the same value with the same relaxation time ( ≈ 560 s at 3 K) for both ZFC and FC processes. This indicates spin freezing below TB and the single molecule process in the explored temperature range (2 K < T < 4 K). The dependence of TB on applied H was also investigated. The decreasing of TB with increasing H can be explained in the frame of barrier reduction in the applied field.
