  The magnetic stability of {\delta}-plutonium is analyzed taking into account
zero-point spin fluctuations. Within the generalized theory of spin
fluctuations described within a simple phenomenological model neglecting its
spatial dispersion we show that zero-point local magnetic moments are giant
(at.Pu) and suppress the magnetic order predicted by ab initio calculations
resulting in the observed paramagnetic state of {\delta}-plutonium.
