The van der Waals–Casimir and Casimir-Polder effects of microscopic particles have been the subject of intensive research in recent years. The zero-point energy quantum fluctuations of the electromagnetic field cause the van der Waals forces; the change of the boundary surface leads to the disturbance of the zero-point energy of the electromagnetic field, and the Casimir force acting on the object can be observed macroscopically. For anisotropic media, the Casimir force may change with the relative direction between the media, and this change leads to the relative rotation, which is called the Casimir torque. The current research on the Casimir effect has involved a variety of anisotropic materials, such as birefringent materials, metamaterials, and anisotropic topological insulators, and the experimental setup for measuring the torque has also been proposed. The Casimir-Polder effect of the two-level atomic system has aroused great interest within the study of quantum optics in recent years. In the presence of boundary of material, the atoms in the ground state or excited state can be affected by the Casimir-Polder potential, and then the Casimir-Polder interaction force emerge, which are also induced by the electromagnetic field of the vacuum fluctuation. Between the boundary of the anisotropic medium and the atom, the Casimir-Polder rotational torque is generated. The vacuum-induced torque effect plays an important role in the fields of physical chemistry, atomic optics and cavity quantum electrodynamics, and it can also result in many potential applications in nanotechnology, such as atomic force microscopes, and reflective elements in atomic optics. The ferrite is a non-metal composite oxide material with ferromagnetism that has been continuously developed in recent years, and its resistivity and dielectric properties show advantages in comparison with conventional magnetic metal. The ferrite has a large magnetic permeability in the high frequency range, so it also has a wide range of uses in the field of high frequency weak current. Ferrite materials have both magnetic absorption and electrical absorption capabilities, and they are superior to other absorbing materials in terms of thickness and bandwidth of the absorbing layer. Therefore, the ferrite absorbing materials are popular materials currently studied. At present, the Casimir repulsion effect and equilibrium recovery effect generated near saturated ferrite, and the Casimir torque of the multilayer ferrite structure system, have been studied and analyzed. Due to the unique electromagnetic properties of the ferrite, the Casimir-Polder torque of nearby atom will be quite different from that of atom in other material environment. In this paper, the Casimir-Polder torque between the two-level atom and the saturated ferrite material plate is calculated, and the specific expression of the Casimir-Polder torque is obtained by using the Green tensor. The theoretical results of the torque under the circularly polarized dipole are presented. The numerical calculation results of the torque under the influence of the atomic position and the transition frequency are given, and the influence of the external magnetic field on the torque is studied as well. The farther the atoms are located from the material plate, the smaller the Casimir-Polder potential becomes, and therefore the rotational torque effect appears weaker, which is also similar to the laws in other Casimir forces or Casimir-Polder interactions. It is found that the Casimir-Polder torque shows a monotonous decreasing behavior with the atomic position and frequency, and it can also be seen that the torque magnitude for the circularly polarized dipole in the plane of certain direction is relatively stronger. Moreover, a non-monotonic inflection point appears in the curve of the torque changing with the external magnetic field, which indicates that when the Casimir-Polder torque is used to control the inherent or existing atomic rotation state, if the torque corresponding to the inflection point in the external-field dependence curve can exactly cancel the original atomic rotation, then further increasing or reducing the intensity of the external field can make the atom rotate in the same direction. The stability of the rotating plane of the torque is also discussed from the perspective of the perturbation imposed on the atomic circular polarization dipole. The Casimir-Polder rotation torque of the atom can be manipulated due to the saturated ferrite, which provides a new way for the control of the rotation state of the two-level atomic system.
