Abstract

We have studied the angle dependent magnetoresistance of the various Bechgaard salts when the magnetic field rotates in the b'c^* plane. Lebed-type resonance is clearly observed for all the compounds both in R_xx and in R_zz. In all cases, conductivity is enhanced at angles proposed by Lebed. (TMTSF)₂ClO₄ shows almost the same behavior as (TMTSF)₂PF₆ in spite of the presence of anion ordering. Only considered is doubling of unit cell along the intermediate conducting direction (b). Conductivity enhancement is very much pronounced in R_zz than in R_xx. The resonance effect is particularly well established in R_zz of (TMTSF)₂ReO₄ where more than seventh resonance can be easily observed. The angles at which resonance takes place can be fitted with the general formula, but only with p/q=odd integers. Also found are additional fast oscillatory parts superposed on the Lebed oscillations.
