P. Grima Gallardo

The analysis will be easier if the sample was known. However, in my experience, the FC curve show a paramagnetic-ferromagnetic phase transition; the hysteresis between ZFC and FC curve suggest the presence of magnetic clusters; and the hump in the ZFC must be due to the unblocking process of the magnetic clusters during heating.

I hope that this preliminary analysis must help you,

Best regards,

Pedro

Dear P.Grima Gallardo,

Sample is Zn doped CeO2. Is the sample also showing superparamagnet behavior ?

Yes, it is possible. You must obtain the value of the mean magnetic moment and compare with Ce.
