77Se NMR investigation of the field-induced spin-density-wave transitions in (TMTSF)2ClO4
Abstract
Complementary 77Se nuclear magnetic resonance (NMR) and electrical transport have been used to correlate the spin density dynamics with the subphases of the field-induced spin density wave (FISDW) ground state in . We find that the peaks in the spin-lattice relaxation rate 1/T1 appear within the metal-FISDW phase boundary and/or at first-order subphase transitions. In the quantum limit above 25 T, the NMR data gives an insight into the FISDW electronic structure.
