Introduction

Low-temperature transport probes Kondo screening after cobalt phthalocyanine molecules are deposited on graphene. Screening persists to around 20 K at high carrier density and weakens as a gate lowers that density.

A closer reading

The gate changes the electronic environment while the magnetic molecules remain on the surface. That separation makes the experiment a useful test of how the graphene carriers couple to localized moments.
