Change in highest intensity peak for Fe3O4 from 311 to 220?

15 May 2020 0 8K Report

In XRD, usually I get the highest peak for Fe3O4 at 311 like most reports but in a few of my characterizations, I am observing the highest intensity peak at 220. Are the particles favoring that orientation or is it a different phase?
