  • Spin-Peierls fluctuations in ▫$(TMTTF)_2Br$▫ studied by pulsed electron spin resonance spin-lattice relaxation
    Zorko, Andrej, 1977- ...
    Spin-Peierls lattice fluctuations were studied in the paramagnetic phase of the antiferromagnetic compound (TMTTF)(2)Br by pulsed electron spin resonance spin-lattice relaxation experiment. The ... relaxation via long-wavelength acoustic phonons was found to coexist with the relaxation via spin fluctuations, becoming the dominant relaxation mechanism in the temperature interval between about 50 K and just above the antiferromagnetic phase transition. This gives direct evidence on the presence of long-wavelength lattice fluctuations in the investigated temperature range.
