Pressure-induced superconductivity beyond magnetic quantum criticality in a Kondo ferromagnet

Quantum phase transitions are an established setting for emergent phenomena driven by strong electronic correlations, including strange metals and unconventional superconductivity. These phenomena have been explored extensively in Kondo-lattice materials tuned to an antiferromagnetic quantum critical point (QCP), but superconductivity emerging near ferromagnetic quantum criticality has not yet been observed, and the conditions under which it occurs in proximity to ferromagnetism remain undetermined. Here, we report a new setting for superconductivity in the ferromagnetic Kondo-lattice material Ce[Formula: see text]CoGe[Formula: see text], which has a ferromagnetic ground state at ambient pressure and evolves to antiferromagnetism under applied pressure. The antiferromagnetic transition is suppressed to a zero-temperature QCP, accompanied by strange-metal behavior. Superconductivity does not occur at the QCP, but instead appears at pressures beyond the magnetic instability. These findings suggest that Ce[Formula: see text]CoGe[Formula: see text] represents a distinct class of correlated materials exhibiting a unique scenario for the emergence of superconductivity, likely associated with unconventional pairing mechanisms beyond spin fluctuations.
