 note = {The mesoporous silica material SBA-15 was prepared with control pore size for use as a nanoparticle synthesis template. The X-ray diffraction results show that the nanopores were ordered in a hexagonal structure. The pore size was controlled by the synthesis conditions. Nanoparticles of the multiferroic compound BiMnO3 with an average size of about 14 nm were successfully synthesized in the pores of SBA-15, and their magnetic properties were investigated. The prepared BiMnO3 nanoparticles showed both antiferromagnetic and ferromagnetic behavior, whereas BiMnO3 bulk crystals consistently showed ferromagnetic behavior. The prepared BiMnO3 nanoparticles exhibited unique magnetic size effects: the appearance of antiferromagnetic behavior and the coexistence of antiferromagnetic and ferromagnetic components.},
