Nuclear spin relaxation in ordered bimetallic chain compounds | Shoji Yamamoto

18 Dec 1999 | Subject: | Strongly Correlated Electrons; Statistical Mechanics | cond-mat.str-el cond-mat.stat-mech | Abstract: | A theoretical interpretation is given to recent proton spin relaxation-time (T_1) measurements on NiCu(C_7H_6N_2O_6)(H_2O)_3$cdot$2H_2O, which is an ideal one-dimensional ferrimagnetic Heisenberg model system of alternating spins 1 and 1/2. The relaxation rate T_1^{-1} is formulated in temrs of the spin-wave theory and is evaluated by the use of a quantum Monte Carlo method. Calculations of the temperature and applied-field (H) dependences of T_1^{-1} are in total agreement with the experimental findings. T_1 behaves as $T_1^{-1}propto H^{-1/2}$, which turns out an indirect observation of the quadratic dispersion relations dominating the low-energy physics of quantum ferrimagnets. | Source: | arXiv, cond-mat/9912340 | Services: | Forum | Review | PDF | Favorites |
