Hello

1. Ferromagnetic Substances - These have all the magnetic domains aligned in one direction and are useful in making permanet  magnets. Eg - Iron, Cobalt
2. Ferrimagnetic Substances - Have magnetic domains unevenly aligned and show minute net magnetic moment. Eg - Ferrites.These transform into paramagnetic substance above Curie Temperature.
3. Antiferro magnetic - Magnetic moments equal and opposite to each other so resultant is zero. Eg - Manganese Oxide and Manganese Dioxide .

Definition and examples are provided above, hope this helps .
