Numerical study on the dynamical susceptibility of the S=1/2 trimerized quantum spin chain

Hijii, Keigo*; Sakai, Toru; Miyashita, Seiji*; Ota, Hitoshi*

We numerically investigated the dynamical susceptibility of the S=1/2 trimerized quantum spin chain. In order to solve the mechanism of the special feature, which is characteristic of the composite spins different from the single S=3/2, observed in the previous high frequency ESR measurement by Prof. Ajiro, we will report the numerical result of the external field dependence and the temperature dependence of the dynamical susceptibility.
