Abstract :
The magnetic properties of MnZn-ferrite films grown on (100) MgO single-crystal substrates using pulsed laser deposition were investigated as a function of composition. The structural and magnetic properties were examined using X-ray diffraction, scanning electron microscopy, X-ray fluorescence, ferrimagnetic resonance, and vibrating sample magnetometry. The films are single phase and well oriented; however, the compositions of the films were measured to be on average about 42% deficient in Zn with excess Mn and Fe. The magnetocrystalline anisotropy field, HA, was found to vary significantly as function of composition such that ⟨001⟩ direction could be changed from a hard to an easy direction with increasing Zn content
