Fig. 2 (Color online) Low-temperature $(T=0.1J_z)$ magnetization and magnetic susceptibility as functions of the longitudinal magnetic field $B_z/J_z$ for several fixed values of the transverse field $B_x/J_z$ , and an arbitrary angle $\theta={\pi}/{30}$ under the condition $b_z=b_x=\lambda=0$. The system is considered in the presence of external homogeneous magnetic fields for which coupling constants have been conventionally taken as $J_{x}=8J_z$ and $J_y=10J_z$. Panels (a) and (c) correspond to the spin-1/2 XYZ model of finite length $N=6$; panels (b) and (d) correspond to the chain of length $N=10$. Insets show the corresponding magnetization and magnetic susceptibility curves for different angle $\theta={\pi}/{10}$.
