“…We assumed that appearance on EPR spectra of resonance lines with the shape of resonance absorption itself instead of the usual derivative of the resonance absorption is due to the resonance excitation of electric quadrupole transitions between states of the dynamical electron quadrupole moment, created by the resonance excitation. Previously, similar changes of the resonance line shapes were detected for the EPR spectra of holmium and ytterbium impurity ions of in forsterite (Mg2SiO4) single crystals [11][12][13].…”

“…It was noted in [10][11][12] that the excitation of electric quadrupole transitions manifests itself in the EPR spectra as an appearance of resonance lines of anomalous shape of the absorption itself instead of the normal first-derivative shape. In addition, it was shown in [12] that the phase of the anomalous lines is shifted relative to the phase of the magnetic field modulation.…”

“…This difference can be caused by at least two reasons. Firstly, the origin of this difference may be related to the discussed in this paper special features of electric quadrupole transitions excited in high-spin systems in a dielectric resonator (ER4118MD5W1) of the EPR spectrometer [8,10,12]. We carried out control measurements of the saturation process of the resonance transitions with this sample in a metal cylindrical resonator (ER4122SHQ (Bruker)).…”

“…It was shown by Salikhov [8] that at resonance excitation of a high-spin system S  1, the dipole orientation of the spin system is transformed into the quadrupole alignment. We used this statement to explain in the article [10] essential change of the line shape of electron paramagnetic resonance (EPR) spectra of impurity Er 3+ ions in Y2SiO5 single crystal at microwave power sufficient to partially saturate resonance transitions. We assumed that appearance on EPR spectra of resonance lines with the shape of resonance absorption itself instead of the usual derivative of the resonance absorption is due to the resonance excitation of electric quadrupole transitions between states of the dynamical electron quadrupole moment, created by the resonance excitation.…”

The unusual resonance lines were observed in continuous wave electron paramagnetic resonance spectra of dimer associate of Cu2+ ions in BaF2 single crystal. The phase of these lines was significantly shifted from the phase of magnetic field modulation. We associate the appearance of these lines with special features of the high-spin electron systems under resonance interaction with microwave electromagnetic field. We take in to account that under resonance excitation of the high-spin electron spin magnetic dipole orientation transforms to quadrupole alignment, and there is the reversible mutual transformation of the dipole and quadrupole degrees of freedom. Simultaneous excitation of magnetic dipole and electric quadrupole resonance transitions in a dielectric resonator of an electron paramagnetic resonance spectrometer results in appearance of the phase shifted resonance lines.

The interaction of polarization singularities (C-points) of a light field in collinearly propagating beams in an isotropic gyrotropic medium with nonlocal nonlinear cubic optical response was studied numerically. The nonlinear self-action significantly affects the transversal polarization and intensity distribution in the propagating beams, while the nonlocality can change the relative weights or the polarization states of the intense peaks in the transversal section. The sum of the topological charges of all of the singularities in the propagating field remains unchanged. The scenario of their interaction is, in general, the same, as in the linear medium, but depending on the nonlinearity character it can either be quickened or slowed down by the increase of the intensity of the incident waves. In the case of very large values of the initial intensity the interaction between the C-points (pairwise creation and annihilation) ceases due to the strong separate self-focusing of circularly polarized components of the field.
