I have synthesizing MnZnFe2O4 (Manganese Zinc Ferrite), and have also have conducted XRD. Now I'm expanding my research for different dopant percentage of Mn & Zn I need to match with standard PXRD of MnZnFe2O4(Manganese Zinc Ferrite).
Hello Senthil,
Below, I attached the CIF file of MnxZn1-xFe2O4 spinel structure. You can find a CIF by using "crystallography open database (COD)" or "Materials project" websites. You can freely access to these two websites. Further, I advice you to understand the distribution of the dopant "Mn" within the unit cell of the pristine ZnFe2O4 spinel because spinel structures are tricky and complicated. There are two types of spinels, namely normal and inverse spinels and also with octa and tetra-hedral sites. You can use "materials studio" or "Vesta" to visualize the distribution of Mn atoms at octa or tetrahedral sites.
Hi there,
First we must saying that spinels structre are very complicate and you would
understand exactly what you are doing so there is 2 ways to find the CIF file :
1__ MATERIALS PROJECT : here you can't find the MZFO but only you find the ZFO or MFO. Then in this case you must choose the ZFO and then replace the Zn atoms with Mn atoms as you like.
In ather hand, you can visit the Crystallography Open Database COD and here you find all the types of spinel and also MZFO.
2__ The second way is just to open the CIF file of ZFO and there you search for the specific atom of Zn and just delete Zn and whrite Mn.

Dear Mr Mohamed,
Can you tell how we can distinguish within the normal and inverse spinel.
We know that if the divalent actions M2+ are in the Tetra site A , the spinal is normal and if in the Octra B it's inverse spinel.
The question is :
How we do normal and inverse spinel with Matrials studio ?
And it's the spinel Mx Zn1_x Fe2 O4 normal or inverse when we import the Cif file from COD ?
Please give us a clear answer and thank you for ever one.
The files from Materials project and few posted here looks like Normal spinel structure.
