Magnetic phase diagram investigation of the organic geometrically frustrated compound TNN¿CH3CN (LT-Part)
The S = 1/2 geometrically frustrated spin systems cases are fascinating due to the interplay between quantum fluctuations and geometric frustration, which is less understood. We have succeeded in synthesizing the new triangular compounds TNN.CH3CN which has a unique two-dimensional structure. Our recent study by means of macroscopic measurements at low temperature and in high magnetic fields revealed that two antiferromagnetically ordered phases exist: One is below 0.25 K at fields below 1.24 T and another is below 0.34 K between 8.45 T and 11.28 T. Above 11.28 T, magnetization reaches full saturation. In the field range 1.24-8.45 T, where the magnetization takes a constant value at 1/3 of full saturation moment no long-range order was observed down to 10 mK. In this proposal we apply for 7 days of beam time on the diffractometer D10, working first with the special Eulerian cradle and dilution insert to collect structural diffraction data in the paramagnetic phase (T ~2K), then to collect data in the magnetically ordered phase (T < 0.25K). These data will allow us to refine the nuclear structure at low temperature and to determine the magnetic structure of the phase
