Formation of ultrathin cobalt ferrite films by interdiffusion ofFe3O4/CoObilayers

Growth and interdiffusion of ultrathin films

The growth and interdiffusion of Ti and Ni on a Mo( 110) surface have been studied by Auger electron spectroscopy (AES), low energy electron diffraction (LEED) and temperature programmed desorption spectroscopy (TPD). Ti grows layer-by-layer upon deposition on MO{ 110) at 115 K, whereas annealing multifaye~ of Ti to 900 K causes formation of Ti three-dimensional clusters. Submonolayer Ti on Mo(...

Atomically flat ultrathin cobalt ferrite islands.

A route for fabricating structurally perfect cobalt ferrite magnetic nanostructures is demonstrated. Ultrathin islands of up to 100 μm(2) with atomically flat surfaces and free from antiphase boundaries are developed. The extremely low defect concentration leads to a robust magnetic order, even for thicknesses below 1 nm, and exceptionally large magnetic domains. This approach allows the evalua...

Growth of ultrathin cobalt oxide films on Pt(111)

Synthesis and Structural Studies of Nickel ‎Doped Cobalt Ferrite Thin Films

   The growth and structural study of Nickel doped Cobalt ferrite thin films on glass substrate using spray pyrolysis technique have been done. The structural studies confirmed the growth of polycrystalline film having cubic structure with Fd3m space group. The x ray density was found to increase with Ni concentration, where as the reduction, in crystalline size, was found in XRD m...
