摘要：

The temperature- and frequency-dependent dielectric relaxation in the quantum nanomagnet Mn-12 acetate and its partially and fully deuterated analogs has been investigated. The four distinct dielectric modes following an activated behavior have been identified in the temperature range from 300-2.8 K and frequency window of 20 Hz-1 MHz. Analysis of the dielectric data in partially and fully deuterated Mn-12 acetate indicates that the three slowest modes can be ascribed to the motion of H2O while the fourth mode to that of the CH3 groups.
