    Abstract

    The stoichiometry and morphology of a model iron oxide magnetic tunnelling junction heterostructure were investigated. The study was carried out by using x-ray photoemmision electron microscopy (X-PEEM) and atomic force microscopy (AFM). The data from AFM evidence islands of width a few μm and height and 10 nm. The results from X-PEEM data show that two types of iron oxide were presented which include the island being Fe 3O 4(111) and the terrace α-Fe 2O 3(0001).
