Abstract Strong electronic correlations often give rise to singular phenomena, such as strange metallicity, which appears in various quantum materials platforms. Understanding the mechanisms behind this universality remains an outstanding challenge, especially because the underlying degrees of freedom can be highly complex and varied. Flat-band systems—especially kagome metals—provide an ideal setting for investigating these properties.

Ni3In is a paramagnetic intermetallic consisting of AB-stacked Ni-kagome networks. Correlated electron behaviors deviating from the Fermi-liquid form have recently been observed in Ni3In bulk single crystals, attributed to stabilization of a partially flat electronic band near the Fermi level.
