摘要
通过中子散射研究了作为典型重铬化物 CeRu_2Si_2 的自旋波动。dynamical susceptibility remarkably well described by the self-consistent renormalization (SCR) theory of the spin fluctuation in a phenomenological way, proving the effectiveness of the theory. The present analysis using the SCR phenomenology has allowed us to determine fourteen exchange constants, which show the long-range nature of the Ruderman-Kittel-Kasuya-Yosida interaction.
