Abstract: A hysteresis of electron spin resonance spectra, which indicates a first-order phase transition, has been revealed in $\alpha'$-(BEDT–TTF)$_2$IBr$_2$ single crystals in the temperature range 15–30 K. Two lines corresponding to the high-temperature and low-temperature phases have been observed in the ESR spectra.
