Abstract

The microwave conductivities σ₁ and dielectric constants ε¹ at 44.5 GHz reveal that the quasi two-dimensional conducting plane is highly anisotropic. In the anomalous metallic state at T_MI (= 8.3 K) < T < T_FM (= 70 K), ε₁^c along c amounts to the order of 10³ and σ₁ ^c becomes more resistive than the dc conductivity. The dispersion in σ₁^c and ε₁^c below T _MI comes from the collective modes due to the charge degrees of freedom.
