## Fermi-surface topology of rare-earth dihydrides

### In: Physical Review B, 2004, vol. 70, no. 165114, p. 1-10

We report high-resolution angle-resolved photoemission experiments on epitaxial thin films of different rare-earth (RE) dihydrides (RE=Gd,La) and of YH2 and ScH2 . It is found through ab initio calculations and confirmed by Fermi surface mapping that the electronic structure becomes very similar upon hydrogenation, rendering the studied dihydrides... More
