Abstract / Bemerkung
Non-equilibrium magnetization process of a S = 1/2 spin triangle in molecular magnet V-15 has been studied by using fast sweeping pulsed magnetic fields. In the up sweep, the magnetization jump of about 1mu(B) is found at the level crossing between the ground S = 1 and the excited S = 3/2 states, while it is about 2mu(B) in the down sweep. The jump in the up sweep is half of that expected in the equilibrium magnetization process. This phenomenon is interpreted by considering the difference of mixing in two degenerated S = 1/2 states with the S = 3/2 state. (C) 2003 Elsevier B.V. All rights reserved.
