Structural Changes of Co Caused a Change of the Solution pH During Chemical Deposition
The phase transformations of the Co lattice are discussed, which determine the anomalous changes in the magnetic properties of chemically deposited Co-P ﬁlms obtained at various pH values. The coercivityof theHc ﬁlms obtainedatlowpHvalues exceeds1kOeand decreasesto several unitsOe in the ﬁlms obtained at high pH values. It is shown that the observed changes in the magnetic properties of Co-P ﬁlms are causedbythe transition of the cobalt crystal lattice to the nanocrystalline state.
