A summary of late-1990s developments in theoretical and experimental studies of fluctuation effects in itinerant electron magnets. This text focuses on novel physical phenomena: soft-mode spin fluctuations and zero-point effects, strong spin anharmonicity, magnetic frustrations in metals, fluctuation effects in Invar alloys and low-dimensional systems. All of these may be important for novel high-technology applications.
