The bipartite lattice based honeycomb quantum magnets, characterized by low coordination numbers, provide a viable route to realize exotic quantum phenomena due to an intricate interplay between competing magnetic interactions, spin-orbit coupling, and crystal electric fields. Here, the authors demonstrate the coexistence of static and dynamic local magnetic fields governed by intraplanar further-neighbor interactions and weak interplanar antiferromagnetic coupling in a 3$d$ transition metal ion based frustrated honeycomb lattice antiferromagnet stabilizing in the XY universality class.
