Fig. 4 Temperature dependences of the specific heat of the 1-D XXZ spin chain under various fixed values of the longitudinal magnetic field $B_z/J_z$. Other external magnetic fields and parameters are taken as $B_x=J_z$, $\theta={\pi}/{30}$, $J_{x}=8J_z$ and $J_y=10J_z$. All applied magnetic fields are also considered as homogeneous fields such that: $b_z=0$, $b_x=0$, and $\lambda=0$. (a) The specific heat of the chain with finite length $N=6$, and (b) $N=10$. Insets show the specific heat of the model in the presence of higher transverse staggered field as $\theta={\pi}/{10}$.
