Abstract
Manganese spinet ferrite (MnFe2O4) films were deposited at the atomic scale. In the depositions, laser pulses alternately impinged MnO and Fe2O3 targets and sequentially deposited thin layers (similar to5 Angstrom) of MnO and Fe2O3 on MgO substrate, which is referred to as "artificial" films. The X-ray diffraction measurements showed that the artificial films were of spinet structure. Auger spectroscopy measurements showed that the chemical composition of the artificial ferrites were consistent with that of standard films deposited using a single target of MnFe2O4. However, extended X-ray absorption fine spectroscopy showed that the artificial growth technique affected the cation distribution to be different from the standard films. As a result, the magnetic properties of the artificial films, including Neel temperature, uniaxial and in-plane anisotropy, were different from the standard films.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
