N2 - We have performed multi-frequency electron spin resonance (ESR) and magnetization measurements on single crystals of the triangular-lattice antiferromagnet CuFe1-xGaxO2 (x=0.000-0.028) to clarify the origin of the shift of the magnetic transition field from an Ising-like four-sublattice phase into an incommensurate phase by doping of Ga3+. As a result, we have succeeded in explaining the shift of transition field by broadening of the lowest excitation branch.
