| Abstract: | We report an EPR study of the chain conductor o-TaS3 in the low temperature charge density wave (CDW) state. The EPR spectrum is attributed to Fe3+ (S=5/2) impurities. A power law for the temperature dependence of the EPR intensity, (T−α with an exponent α∼0.8) found below ∼30 K is very close to that previously found in magnetic susceptibility measurements. The possible role of these impurities in the susceptibility data are discussed. |
