Abstract: The results of studying the influence of the thickness of La$_{0.7}$Sr$_{0.3}$MnO$_3$ films obtained by magnetron sputtering on (110) NdGaO$_3$ substrates on the magnetic and crystallographic properties using ferromagnetic resonance and X-ray spectroscopy are presented. The dependences of the uniaxial and cubic anisotropy fields on the sample thickness are established. Furthermore, it is shown that the magnetic and crystallographic properties of a film obtained by magnetron sputtering strongly depend on the target region from which it is made. The results obtained will be useful for interpreting the experimental data and creating a series of samples.

Keywords: ferromagnet, magnetic anisotropy, ferromagnetic resonance.
