摘要

The zero point oscillation state of hole carriers confined in block layer potential of La_(2-χ)Sr_χCuO_4 is similar to the zero point state in a Landau gauge, when the effective "magnetic field" is greater than 10~3T. It is shown that a strong effective field and space charge form layered fractional quantum Hall effect (FQHE) state for c-axis oriented La_(2-χ)Sr_χ.CuO_4 films with localization character, for which there is an anomalous dielectric polarization with negative dielectric constant is expected to appear. Experimental study of the dielectric properties of c-axis oriented La_(2-χ)Sr_χCuO_4 film with oxygen deficiency is made by "ac method" and "dc method". The negativeness of the electric field in La_(2-χ)Sr_χCuO_4 film and of the film capacitance are observed with hysteretic polarization.
