Abstract
We have observed a strong sensitivity to low magnetic field ( $\rm H<0.5$ T) of the low-temperature specific heat of (TMTSF) ₂PF ₆ in its spin-density wave ground state. The mostly pronounced manifestation is a sharp maximum at $\rm H = 0.2$ T in the amplitude of Shottky anomaly contribution which dominates the heat capacity below 0.3 K. This effect is independent of the field direction for H // a or b' crystal axis. Key words. One-dimensional Conductors, Density waves, Glassy State, Magnetic field.
