XRD results shows peaks due gama-Fe2O3/Fe3O4 phase, M-H curves show superparamagnetic behaviour at 300 K and ferromagnetic behaviour at 5 K. But ZFC curve shows a small hump around 266 K for morin transition.

Maghemite Fe2O3 is biocompatible and showing Morin transition above 5K (did not exhibit the Morin transition down to 5 K)
Hematite is an antiferromagnetic material below the Morin transition at 260 K.

Yes, but may be you can do a ExBias (MH a low temperature on FC condition) measure to check coexistence of two phases.
