Spin-Wave Description of Nuclear Spin-Lattice Relaxation in Mn_{12}O_{12} Acetate
Shoji Yamamoto, Takashi Nakanishi
In response to recent nuclear-magnetic-resonance (NMR) measurements on the molecular cluster Mn_{12}O_{12} acetate, we study the nuclear spin-lattice relaxation rate 1/T_1 developi…

Intrinsic double-peak structure of the specific heat in low-dimensional quantum ferrimagnets
Takashi Nakanishi, Shoji Yamamoto
Motivated by recent magnetic measurements on A3Cu3(PO4)4 (A=Ca,Sr) and Cu(3-Clpy)2(N3)2 (3-Clpy=3-Chloropyridine), both of which behave like one-dimensional ferrimagnets, we extens…

Low-Temperature Properties of Quasi-One-Dimensional Molecule-Based Ferromagnets
Takashi Nakanishi, Shoji Yamamoto, Toru Sakai
Quantum and thermal behaviors of low-dimensional mixed-spin systems are investigated with particular emphasis on the design of molecule-based ferromagnets. One can obtain a molecul…
