The Effect of Magnesium Substitution and Sintering Temperature on the Structural and Magnetic Properties of Manganese- Magnesium Ferrite
Magnesium-manganese ferrite nanopowders (MgxMn1-xFe2O4, x=0.0 up to 1 with step 0.2) were prepared by coprecipitation method. The as-prepared samples were pressed with hydrolic press to form a pellet and were sintered in 900, 1050 and 1250˚C. Scanning Tunneling Microscope (STM) images showed the par...
