EFFECTS OF ISOSTATIC PRESSURE ON THE MAGNETIC PROPERTIES OF POLY(3-HEXYLTHIOPHENE)

Abstract

We have observed the variation of the magnetic saturation, and Curie temperature (TC) in samples of the poly(3- hexylthiophene) doped with ClO4 isostatically pressed. We attribute this behaviorto the continuous variation of the interchain interaction induced by different pressures used during the sample preparation. We believe that the pressure induces an increase in exchange interaction interchains because of the reduction of the distance interchain, contributing to the increase in the ferromagnetic behavior observed in the samples.
