I can't answer your question as it is beyond my understanding.

Allwin Sudhakaran There's so much going on! Let me try give you some tips...

You are dealing with Hysteresis curves obtained from VSM, right?

You should study what is happening with your nanocomposite (i.e the difference between the A1 and S1, for instance), I can see that there are some samples that you can observe double and triple layers and loop and others that it seems that there is no loop, and the material is superparamagnetic. Some of them are hard and soft magnetic materials.

But you have to study what this curves is telling you when it comes to: Coercivity, Remanescence, Saturation in both directions

I am going to attach some material for you in order to help you

Dear Allwin,

the "complex" curves you obtained are probably the result of the combination of the magnetic properties of two materials, a hard ferrimagnetic one (high coercivity probably due to the hexaferrite) with a soft one (low coercivity, probably due to the spinel ferrite). If you measure the sample at high temperature perhaps you will be able to delete the magnetic contribution of the material having the lower Curie temperature. You will then obtain a conventional hysteresis curve as for some of the pictures you have given.

Have a good work.

Philippe.
