Electronic inhomogeneity in heavy Fermions*

The experimentally determined superconducting condensation energy of La-doped CeCoIn$_{5}$ is interpreted to show that the superconducting fraction decreases linearly with La concentration, consistent with the measured residual normal fraction seen in the electronic specific gamma remaining in the superconducting state as T $\to $ 0K. The In NQR data is also discussed. Our result points to an electronically inhomogeneous state that appears to be common to doped heavy Fermion materials near a quantum critical point.
