Fig. 5 (Color online) Temperature dependences of the specific heat of the 1-D XYZ spin chain under various fixed values of the longitudinal magnetic field $B_z/J_z$. Other external magnetic fields and parameters are as in Fig. 4. Here, all applied magnetic fields have been considered as inhomogeneous fields such that: $b_z=0.6J_z$, $b_x=0.3J_z$, and $\lambda=J_z$. (a) The specific heat as a function of the temperature for the chain with finite length $N=6$, and (b) $N=10$. Insets show the specific heat of the model versus temperature in the presence of higher transverse staggered field as $\theta={\pi}/{10}$.
