In this report, we compare the analysis of electron spin resonance (ESR) studies of Berezinskii-Kosterlitz-Thouless (BKT) correlations in the spin S = 1 Ni2+-based layered honeycomb antiferromagnets BaNi2X2O8 with X = V, P and As. Moreover, we investigate the effect of doping on the BKT correlations by the substitution of Ni2+ by spin S = 1/2 Cu2+ ions in BaNi2V2O8.
