Question

what metal oxides show ferromagnetism​

Answer 1

$\huge\bold\red{HELLO!}$

In conclusion, we have shown that nanoparticles of metal oxides such as CeO2, Al2O3, ZnO, In2O3 and SnO2, exhibit room- temperature ferromagnetism whereas the corresponding bulk oxides exhibit diamagnetism.

Answer 2

Answer:

Ferromagnetic metals are strongly attracted by a magnetic force. The common ferromagnetic metals include iron, nickel, cobalt, gadolinium, dysprosium and alloys such as steel that also contain specific ferromagnetic metals such as iron or nickel. Ferromagnetic metals are commonly used to make permanent magnets.
