摘要：
An analytical expression that quantifies the suppression of exchange-enhanced local spin-density fluctuations with magnetic field for temperatures in the vicinity of, but still away from, the Curie point in weak itinerant-electron magnets has been derived within the framework of the spin fluctuation model. Our recent magnetization data on the archetype weak itinerant-electron ferromagnet Ni3Al testify to the validity of the theoretical predictions based on the presently derived expression.
