Quantum fluctuations of the magnetization in high spin molecules - a mu SR study

Abstract:

Using zero field (ZF) and longitudinal field (LF) mu SR we study the magnetic properties of high spin molecules (HSM) with spin S = 15/2 and 27/2. The LF-mu SR at very low temperatures suggests that in both our samples dynamical field fluctuations are responsible for the muon relaxation. The relaxation rate lambda increases as the temperature decreases and then saturates below T < T-c indicating that the dynamics is of quantum nature. The fluctuation rate at T --> 0 of the different sam...
