摘要：

Zero-point spin fluctuations (SF) are shown to give rise to strong spin anharmonicity neglected in the conventional theory of itinerant magnetism based on the weak SF coupling constraint. A theory is presented generalizing the quantum Ginzburg-Landau approach to account for large zero-point SF and spin anharmonicity effects.
