Comparison of Fermi surface and band structure between CePt₂In₇ and CeCoIn₅. (a) Measured band structure of CePt₂In₇ which is a second derivative image of the original data with respect to energy. (b) Measured band structure of CeCoIn₅ which is a second derivative image of the original data with respect to energy. The location of the momentum cuts for (a) and (b) is shown by the pink lines in the inset on the right of (b). (c) Measured Fermi surface of CePt₂In₇. (d) Measured Fermi surface of CeCoIn₅.^[22]
