  The effect of quantum coherence involving macroscopic degree of freedom, and
occurring in systems far larger than individual atoms are one of the topical
fields in modern physics. Because of material dispersion, a phenomenological
approach to macroscopic quantum electrodynamics, where no canonical formulation
is attempted, is used. The problem becomes more complicated when geometrical
forms of a material structure have to be taken into consideration. Magnetic
dipolar mode (MDM) oscillations in a magnetically saturated quasi 2D ferrite
disk are macroscopically quantized states. In this ferrimagnetic structure,
long range dipole dipole correlation in positions of electron spins can be
treated in terms of collective excitations of a system as a whole. The near
fields in the proximity of a MDM ferrite disk have space and time symmetry
breakings. Such MDM-originated fields, called magnetoelectric (ME) fields,carry
both spin and orbital angular momentums. By virtue of unique topology, ME
fields are different from free space electromagnetic (EM) fields. The ME fields
are quantum fluctuations in vacuum. We call these quantized states ME photons.
There are not virtual EM photons. We show that energy, spin and orbital angular
momenta of MDM oscillations constitute the key physical quantities that
characterize the ME field configurations. We show that vacuum can induce a
Casimir torque between a MDM ferrite disk, metal walls, and dielectric samples.
