  Magnetic and thermodynamic properties of the anisotropic XYZ spin-1/2 finite
chain under both homogeneous and inhomogeneous magnetic fields are
theoretically studied at low temperature. Using exact diagonalization method
(ED), we study the magnetization, magnetic susceptibility and specific heat of
the model characterized in terms of the finite correlation length in the
presence of three different magnetic fields including longitudinal, transverse
and transverse staggered magnetic fields. The magnetization, susceptibility and
the specific heat of the model are investigated under two conditions
separately: I) when the model is putted in the presence of homogeneous magnetic
fields; II) when finite inhomogeneities are considered for all applied magnetic
fields in the Hamiltonian. We show that for the finite-size XYZ chains at low
temperature, the evident magnetization plateaus gradually convert to their
counterpart quasi-plateaus when the transverse magnetic field increases.
Moreover, the influence of the transverse and staggered transverse magnetic
fields, and their corresponding inhomogeneities on the magnetization process,
magnetic susceptibility, and specific heat are reported in detail. Our exact
results illustrate that by altering the inhomogeneity parameters, magnetization
plateaus gradually convert to their counterpart quasi-plateaus. The specific
heat manifests Schottky-type maximum, double-peak and triple-peak, as well as,
transformation between them by varying considered inhomogeneity parameters in
the Hamiltonian.
