• In this report, we examined diamagnetic and anti-diamagnetic (paramagnetic) properties of magnetosonic modes in anisotropic fluid pressure condition by incorporating double adiabatic equations of state. In the context of liner perturbations, it is found that there appear two wave modes corresponding to a slow phase velocity and a fast phase velocity as is resembled to those in isotropic plasmas. For the fast phase velocity mode, pressure perturbations and field perturbations exhibited paramagnetic relations, similarly to isotropic plasmas. For the slow phase velocity mode, paramagnetic properties appear, unlike the isotropic case, at higher plasma beta part of lower pressure anisotropy (perpendicular/parallel) region.
