NMR evidence for a "generalized spin-Peierls transition" in the high magnetic field phase of the spin-ladder Cu2(C5N2H12)2Cl4

H. Mayaffre, M. Horvatic, C. Berthier +4

The magnetic field-induced 3D ordered phase of the two-leg spin-ladder Cu2(C5N2H12)2Cl4 has been probed through measurements of 1H NMR spectra and 1/T1 in the temperature range 70~…
