  1. Comparison of the characteristic temperatures of charge order formation (Tco) and the temperatures below which the TRS is broken, either at zero (\({T}_{{{\rm{ZF}}}}^{*}\)) or high magnetic field (\({T}_{{{\rm{HF}}}}^{*}\)). The absolute increase in the zero-field muon spin relaxation rate below \({T}_{{{\rm{ZF}}}}^{*}\), denoted as ΔΓZF, is also shown for various systems.
