Evidence for multimagnon-mediated nuclear spin relaxation in the intertwining double-cain ferrimagnet
Shoji Yamamoto, Hiromitsu Hori, Yuji Furukawa +6
The nuclear spin-lattice relaxation time of nuclei in the title compound is measured for the first time and interpreted in terms of a modified spin-wave theory. We e…
Low-temperature thermodynamics of one-dimensional alternating-spin Heisenberg ferromagnets
Shoji Yamamoto, Hiromitsu Hori
Motivated by a novel bimetallic chain compound in which alternating magnetic centers are ferromagnetically coupled, we investigate thermodynamic properties of one-dimensional spin-…
Modified spin-wave theory of nuclear magnetic relaxation in one-dimensional quantum ferrimagnets: Three-magnon versus Raman processes
Shoji Yamamoto, Hiromitsu Hori
Nuclear spin-lattice relaxation in one-dimensional Heisenberg ferrimagnets is studied by means of a modified spin-wave theory. Calculating beyond the first-order mechanism, where a…
Nuclear Magnetic Relaxation in the Ferrimagnetic Chain Compound NiCu(C_7_H_6_N_2_O_6_)(H_2_O)_3_2H_2_O: Three-Magnon Scattering?
Hiromitsu Hori, Shoji Yamamoto
Recent proton spin-lattice relaxation-time (T_1_) measurements on the ferrimagnetic chain compound NiCu(C_7_H_6_N_2_O_6_)(H_2_O)_3_2H_2_O are explained by an elaborately modified s…
Nuclear Spin-Lattice Relaxation in One-Dimensional Heisenberg Ferrimagnets: Three-Magnon versus Raman Processes
Hiromitsu Hori, Shoji Yamamoto
Nuclear spin-lattice relaxation in one-dimensional Heisenberg ferrimagnets is studied by means of a modified spin-wave theory. We consider the second-order process, where a nuclear…
Nuclear Magnetic Relaxation in the Haldane-Gap Antiferromagnet Ni(C_2_H_8_N_2_)_2_NO_2_(ClO_4_)
Shoji Yamamoto, Hiromitsu Hori
A new theory is proposed to interpret nuclear spin-lattice relaxation-time (T_1_) measurements on the spin-1 quasi-one-dimensional Heisenberg antiferromagnet Ni(C_2_H_8_N_2_)_2_NO_…
