  A nearly free electron metal and a Mott insulating state can be thought of as
opposite ends of possibilities for the motion of electrons in a solid. In the
magnetic oxide metal PdCrO$_{2}$, these two coexist as alternating layers.
Using angle resolved photoemission, we surprisingly find sharp band-like
features in the one-electron removal spectral function of the correlated
subsystem. We show that these arise because a hole created in the Mott layer
moves to and propagates in the metallic layer while retaining memory of the
Mott layer's magnetism. This picture is quantitatively supported by a strong
coupling analysis capturing the physics of PdCrO$_{2}$ in terms of a Kondo
lattice Hamiltonian. Our findings open new routes to use the non-magnetic probe
of photoemission to gain insights into the spin-susceptibility of correlated
electron systems.
