چکیده انگلیسی
In quasi-two-dimensional systems the dipolar interaction can play an essential role in determine the magnetic properties. In a case of magnetic-dipolar modes in a normally magnetized thin-film ferrite disk, the oscillations can be considered as the motion process of certain quasiparticles-the light magnons-having quantization of energy and characterizing by effective masses depending on the energy levels. One of the features of magnetic-dipolar oscillations in a normally magnetized ferrite disk resonator is the presence of helicoidal surface magnetic currents. These currents lead to the parity violation effects in magnetic-dipolar oscillations and appearance of anapole moments. Recent experiments show that magnetic-dipolar oscillations in a normally magnetized ferrite disk are strongly affected by a normal component of the external RF electric field. The anapole-moment model gives very convincing arguments for explaining these experimental data.
