| Abstract: | The magnetoresistance in spin-ordered state of quasi-one-dimensional (TMTSF)2PF6 has been studied. Both the frequency and anisotropy of the magnetoresistance oscillations are found to be independent of
temperature; this proves the temperature independence of the geometry of two-dimensional closed contours at the Fermi level.
At the same time, the oscillation amplitude decreases with the temperature, indicating the depopulation of the closed contours
in the T = 0 limit. An explanation for the above seemingly controversial results has been proposed.
