Electronic structure of the quadrupolar ordered heavy-fermion compound YbRu2Ge2 measured by angle-resolved photoemission

H. Pfau, E. W. Rosenberg, P. Massat +5

We studied the electronic structure of the heavy fermion compound Yb(Ru${}_{1-x}$Rh${}_x$)${}_2$Ge${}_2$ with $x=0$ and nominally $x=0.125$ using ARPES and LDA calculations. We find a va…
