DC resistivity and electron spin resonance (ESR) measurements have been performed on the two-dimensionalorganicconductor k-(BEDT-TTF)2Hg(SCN)2Cl. Due to electronic correlations, the compound undergoes a transition from a metallic to an insulating state at TMI= 34 K.The ESR parameters exhibit a drastic change below Tafm=27K that evidences a magnetic phase transition. Int his low-temperature state, we observe the characteristics of antiferromagnetic resonances in the angular dependence of the g-value.
