概要

• 論文の詳細を見る

• Angle-resolved specific heat measurements are preformed on the f-electron superconductor CeRu_2 in rotating magnetic fields 0.5≤H≤6T at various temperatures 0.3≤T≤2K. In the whole H-T range examined, a clear 4-fold oscillation is observed and yields the gap minimum (maximum) located to <110> (<100>) in the cubic crystal with the ratio Δ_<min>/Δ_<max>〜0.3. The oscillation amplitude landscape in H-T plane with a local maximum is explained by a microscopic theory, pointing to a new spectroscopy for gap determination.
