It is know that bifurcation of FC-ZFC generally explains Spin glass behavior or Superparamagnetism in samples. I am working on thin films I have done Curie-Weiss fitting it shows its ferromagnetic coupled. But HC Vs T is neither exponentially dependent nor linear with square root of Temperature. So, I am unable to conclude whether it is spin glass or superparamagnetic. I will be very thankful if you can give an idea about its magnetic state and relatable references.

Thank you in advance.
