Abstract
Using a capacitance bridge with a phase sensitive detection at frequencies f (=ω/2π)=101 to 105 Hz, we have measured the complex dielectric constant ε(ω)=ε1(ω)+iε2(ω) along the c-axis in the antiferromagnetic insulating state of λ-(BEDT-TSF)2FeCl4 below TMI=8.3 K. The magnitude of ε1 is quite large in the order of 103 to 104 in contrast to 45 at microwave frequencies. Both ε1 and ε2 increase very drastically on approaching to TMI, suggesting some divergent behavior near TMI.
