Description
Summary:DC resistivity and electron spin resonance (ESR) measurements have been performed on the two-dimensional organic conductor Kappa - ( BEDT-TTF ) 2 Hg ( SCN ) 2 Cl . Due to electronic correlations, the compound undergoes a transition from a metallic to an insulating state at T MI = 34 K . The ESR parameters exhibit a drastic change below T afm = 27 K that evidences a magnetic phase transition. In this low-temperature state, we observe the characteristics of antiferromagnetic resonances in the angular dependence of the g-value.
