We have carried out high-resolution angle-resolved photoemission measurements on the Cebased heavy fermion compound CePt₂In₇ that exhibits stronger two-dimensional character than the prototypical heavy fermion system CeCoIn₅. Multiple Fermi surface sheets and a complex band structure are clearly resolved. We have also performed detailed band structure calculations on CePt₂In₇. The good agreement found between our measurements and the calculations suggests that the band renormalization effect is rather weak in CePt₂In₇. A comparison of the common features of the electronic structure of CePt₂In₇ and CeCoIn5 indicates that CeCoIn₅ shows a much stronger band renormalization effect than CePt₂In₇. These results provide new information for understanding the heavy fermion behaviors and unconventional superconductivity in Ce-based heavy fermion systems.
