Zusammenfassung: | Low-dimensional organic conductors show a rich phase diagram, which has, despite all efforts, still some unexplored regions. Charge ordered phases present in many compounds of the (TMTTF)2X family are typically studied with their unique electronic properties in mind. An influence on the spin arrangement is, however, not expected at first glance. Here, we report temperature and angle dependent electron spin resonance (ESR) measurements on the quasi one-dimensional organic conductor (TMTTF)2NO3. We found that the (TMTTF)2NO3 compound develops a peculiar anisotropy with a doubled periodicity (ab′-plane) of the ESR linewidth below about TCO=(250±10) K. This behavior is similar to observations in the related compounds (TMTTF)2X (X=PF6, SbF6 and AsF6), where it has been attributed to relaxation processes of magnetically inequivalent sites in the charge-ordered state. For the structural analogous (TMTTF)2ClO4, known for the absence of charge order, such angular dependence of the ESR signal is not observed. Therefore, our ESR measurements lead us to conclude that a charge-order phase is stabilized in the title compound below TCO≈250 K. |
