Abstract

Fe_xO_y hollow nanospheres were synthesized inside cage type mesoporous silica LP-FDU-12 through nanocasting. The sample was reduced to Fe₃O₄ and then further oxidized to γ-Fe₂O₃ with little changes in morphology and size. The Verwey transition is observed in the Fe₃O₄ hollow nanosphere system for the first time with magnetic measurement.
