Field-Orientation Dependence of Low-Energy Quasiparticle Excitations in the Heavy-Electron Superconductor UBe13

Yusei Shimizu, Shunichiro Kittaka, Toshiro Sakakibara +5

Low-energy quasiparticle excitations in the superconducting (SC) state of UBe${}_{13}$ were studied by means of specific-heat ($C$) measurements in a rotating field. Quite unexpected…
