Mechanisms for Non-Trivial Magnetization Plateaux of an S=1 Frustrated Spin Ladder
Kiyomi Okamoto, Nobuhisa Okazaki, Tôru Sakai
We investigate the non-trivial magnetization plateau at 1/4 of the saturation magnetization of S=1 spin ladder, especially with reference to recent experimental results on a new or…
Magnetization Plateau in the S=1 Spin Ladder with Competing Interactions
Nobuhisa Okazaki, Kiyomi Okamoto, Toru Sakai
Very recently a non-trivial magnetization plateau at 1/4 of the saturation magnetization was observed in the S=1 spin ladder BIP-TENO. In our previous work we proposed a possible m…
Magnetization Plateau of an S=1 Frustrated Spin Ladder
Kiyomi Okamoto, Nobuhisa Okazaki, Tôru Sakai
We study the magnetization plateau at 1/4 of the saturation magnetization of the S=1 antiferromagnetic spin ladder both analytically and numerically, with the aim of explaining rec…
Field-Induced Gaps in the Frustrated Spin Ladder
Nobuhisa Okazaki, Kiyomi Okamoto, Toru Sakai
We study the magnetization process of the antiferromagnetic spin ladder in the presence of the second and the third-neighbor couplings which lead to frustration with the ty…
Magnetic properties of frustrated spin ladder
Toru Sakai, Nobuhisa Okazaki
The magnetic properties of the antiferromagnetic spin ladder with the next-nearest neighbor interaction, particularly under external field, are investigated by the exact diagonaliz…
Magnetization Plateau in the Frustrated Spin Ladder
Nobuhisa Okazaki, Junji Miyoshi, Toru Sakai
The magnetization process of the S=1/2 antiferromagnetic spin ladder at T=0 is studied by the exact diagonalization of finite clusters and size scaling analyses. It is found that a…
