Abstract

In this paper we describe experiments involving measurements of the dependence on time of the thermoremanence magnetization of 2-dimensional random magnets. The low temperature values for the magnetic viscosity agree well with both current theories of tunneling of the magnetization vector (Chudnovsky et al.) and the work of Grabert et al. who predicted that the transition from classical to quantum regime is rather sharp for undamped systems.
