Abstract

We analyze the magnetic stability of the ground state of magnetic systems, taking into account strongly coupled zero-point spin fluctuations. The formalism is applied to the elemental 3d-metals Fe and Ni and to two phases of the 5f-metal Pu. Strong suppression of local magnetism due to spin fluctuations is obtained for x alpha- Pu. Such inclusion of spin fluctuations changes the character of the magnetism in alpha-Pu from localized to itinerant. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3549656]
