Magnetic properties of ultrafine M-type hexaferrite nanoparticles with tunable sizes prepared by glass-ceramic method

Ultrafine M-type hexaferrite Ba 1- x Sr x Fe₁₂O₁₉ nanoparticles ( x = 0–0.8) were synthesized via a glass-ceramic route where the grain size was controlled by controlling the BaO/SrO ratio in precursor glasses. Sr 2+ substitution induces lattice contraction and reduces the averag...
