ABSTRACT Chiral magneto‐phononic modes—hybridized vibrational states that carry angular momentum through coupling with magnetic degrees of freedom—offer a novel route for controlling magnetism and enabling topological phononics. Here, we report the magnetic switching of these hybridized chiral phonons, Zn x Fe 2‐ x Mo 3 O 8 , using helicity‐resolved magneto‐Raman spectroscopy. By tuning the Zn concentration across antiferromagnetic and ferrimagnetic regimes, we uncover two key phenomena: (i) a g
