Spin excitation of the Heisenberg antiferromagnet with frustration: from the bounce-lattice antiferromagnet through the maple-leaf-lattice antiferromagnet to the exact-dimer system
Hiroki Nakano, Toru Sakai
The spin-S Heisenberg antiferromagnet on the two-dimensional lattice is investigated for S=1/2 and S=1. We consider interaction at isolated dimers () and interaction bon…
Magnetization Plateau of the Distorted Diamond Spin Chain with Ferromagnetic Interaction
Masaru Hashimoto, Koki Doi, Tomoki Houda +4
The magnetization process of the distorted diamond spin chain with ferromagnetic interactions is investigated using the numerical diagonalization of finite-size clusters. T…
