Abstract

The heavy-fermion compound CeRu₂Si₂ is a Pauli paramagnetic metal with a large electronic specific heat coefficient of γ to approximately 370 mJ/mol K². Microwave cavity transmission experiments were performed to clarify the dynamic response caused by the dielectric function εω and the magnetic permeability μω in the compound. The anomaly for both εω and μω was observed at the metamagnetic field H_M = 7.7 T below 1 K, whereas the B-T phase diagram provided by the dynamic response was found to be different for the static one.
