    Opis:
    The main issue addressed in present study is exchange coupling modification between ferromagnetic layers through non-magnetic spacer layers using extra ultra-thin ferromagnetic layers (Co). In order to achieve this goal, we prepared Cr(50 Å) / Py(20 Å) / Co(5 Å) / Cr(7, 10, 13 Å) / Co(5 Å) / Py (30 Å) / Cr(50Å) / Si using magnetron sputtering at UHV conditions and characterized by Ferromagnetic Resonance (FMR) technique. As the present study results were compared to our previous study on (Py/Cr), the exchange coupling energy was increased ten times with the cobalt thin layer

    Opis:
    We focused on the interaction between two ferromagnetic cobalt layers through a non-magnetic titanium layer. The magnetic properties of the structure were characterized by ferromagnetic resonance technique. The data were collected as a function of non-magnetic titanium layer thickness. Co/Ti multilayer (Ti(50 Å)/Co(45 Å)/Ti(2-40 Å)/Co(40 Å)/Ti(100 Å)) films were grown onto naturally oxidized p-type single crystal Si (100) substrate at UHV condition with magnetron sputtering system at room temperature. The thickness of Ti spacer layer ranges from 2 to 40 Å with 2 Å steps. We did not observe usual optic and acoustic modes; instead we had two broad overlapped peaks for the films ranged from 6 Å to 40 Å. One interesting result was the high anisotropic resonance field values for these films. Exchange coupling between ferromagnetic layers causes shift on resonance field values but these shifts in our samples were much larger than expected. This large anisotropic behavior is not clear at the moment. Our theoretical model was not able to determine a value for the exchange coupling parameter. One reason can be the close thickness values for Co sublayers. The other reason can be the Ti non-magnetic layer. If titanium did not grow layer by layer on cobalt, the cobalt ferromagnetic layers may behave as a single layer. As a result one cannot observe exchange interaction between ferromagnetic layers through non-magnetic spacer.

    Opis:
    The magnetic and elastic properties of epitaxially grown Mo/Co/Au trilayer systems were investigated by the Brillouin light scattering and a ferromagnetic resonance. Using both experimental methods the perpendicular uniaxial anisotropy and the effective in-plane twofold anisotropy contributions were determined as the function of the cobalt thicknesses. Acoustic phonons analysis shows that the elastic constants are decreased with increasing cobalt layer thicknesses.

    Opis:
    We report ferromagnetic resonance study of the magnetization reversal in the exchange-coupled MnO/(Ga,Mn)As system. The low-field parts of ferromagnetic resonance spectra measured along [1/10] and [100] directions of (Ga,Mn)As were combined into hysteresis loops, which under field-cooling conditions similarly to SQUID loops are shifted toward negative magnetic fields. The magnetization reversal process revealed by the loops occurred remarkably asymmetric for both sample configurations.

    Opis:
    Using cavity ferromagnetic resonance and vector network analyzer ferromagnetic resonance unidirectional, uniaxial and rotatable anisotropies were determined in permalloy(30 nm)/NiMn(56 nm). Resonance field dependence on in-plane angle clearly shows unidirectional and uniaxial anisotropy. Rotatable anisotropy, which acts as internal magnetic field independent of a direction of external magnetic field, is observed on vector network analyzer ferromagnetic resonance as upward shift of the resonance frequency of Py/NiMn compared to Py film. Even for a small exchange bias field, this shift is significantly large.

The measurements were performed on the series of samples with varying thicknesses d$\text{}_{GaAs}$ of nonmagnetic GaAs spacer, established d$\text{}_{GaAs}$-dependent extent of weak and strong interlayer exchange coupling, judging on the observation of one or two ferromagnetic resonance modes.

    Opis:
    In this work we report results of ferromagnetic resonance studies of a 6% 15nm (Ga,Mn)As layer, deposited on (001)-oriented GaAs. The measurements were performed with in-plane oriented magnetic field, in the temperature range between 5 K and 120 K. We observe a temperature induced reorientation of the effective in-plane easy axis from $[\overline{1}10]$ to [110] direction close to the Curie temperature. The behavior of magnetization is described by anisotropy fields, $H_{eff}$ (=4π $M-H_{2⊥}$), $H_{2∥},$ and $H_{4∥}$. In order to precisely investigate this reorientation, numerical values of anisotropy fields have been determined using powerful - but still largely unknown - interval calculations. In simulation mode this approach makes possible to find all the resonance fields for arbitrarily oriented sample, which is generally intractable analytically. In "fitting" mode we effectively utilize full experimental information, not only those measurements performed in special, distinguished directions, to reliably estimate the values of important physical parameters as well as their uncertainties and correlations.
