Even after few repetitions..I am getting similar results. Is is due to organic components?
what conditions are you using? Maybe your analysis is being carried too fast, and your peaks are convoluting
Dr. Sunil Pandey if measuring conditions are correct, broad peaks in XRD suggest amorphous nature of the materials.
whether "organic components"can make the FeO's XRD completely amorphous, is the matter of discussion.
But, if there are too many functional groups (i.e. organic molecules) then those organic moieties will be attached to the Fe or O atoms causing disturbance in the atomic scal/ That disturbance can result in broad peaks.
Dear Dr. Sunil Pandey ,
the XRD pattern looks quite 'amorphous'; such pattern is known from water...
The similarity is outstanding.
Please see for example the following link:

To my opinion the pattern could be due to any solvent or even water or organic molecules surrounding the NPs as already mentioned by Syed Waqar Hasan and by you.
By the way: did you use a Cr- or a Fe x-ray target in order to reduce Fe K-fluorescence? Cu target will give Fe fluorescence. Fluorescence will cause back ground, but is not resposible for your broad peak(s).
Humps show presence of morphous phase. If you have followed accurate synthesis process or processing conditions that is maybe due to the substrate material or thickness of your sample. That is may be due to glass or some other organic material.
It must be Amorphous. I too agree Thanks a lot for valuable inputs
Before stating it as must be amorphous, I'd go for a HRTEM to see if the crystallites are not just too small for bringing a discrete pattern.
