Nanocrystalline zinc ferrite films studied by magneto-optical spectroscopy

Original language description

Ferrimagnetic Zn-ferrite (ZnFe2O4) films can be grown with the ferromagnetic resonance linewidth of 40 Oe at 9.5 GHz without going through a high temperature processing. This presents interest for applications. The work deals with laser ablated ZnFe2O4 films deposited at O-2 pressure of 0.16 mbar onto fused quartz substrates. The films about 120 nm thick are nanocrystalline and their spontaneous magnetization, 4 pi Ms, depends on the nanograin size, which is controlled by the substrate temperature (T-s). At T-s approximate to 350 degrees C, where the grain distribution peaks around similar to 20-30 nm, the room temperature 4 pi Ms reaches a maximum of similar to 2.3 kG. The films were studied by magnetooptical polar Kerr effect (MOKE) spectroscopy at photon energies between 1 and 5 eV. The complementary characteristics were provided by spectral ellipsometry (SE). Both the SE and MOKE spectra confirmed ferrimagnetic ordering. The structural details correspond to those observed in MgFe2O
