Pressure dependence of the angular magnetoresistance of (TMTSF)(2)PF6

Abstract

An anomalous crossover has been reported in the background of angular magnetoresistance of (TMTSF)(2)PF6 as pressure increases. When a magnetic field rotated in the plane perpendicular to the a-axis, the background of the interlayer resistance R-zz was concave around c(')-axis at low pressure but became convex above 10 kbar. However, our extensive experiments revealed that only one form of background resistance occurred in a sample regardless of pressure. The deceptive crossover may be attributed to the possible mixing of intralayer resistivity component(s) to the interlayer resistivity component.
