    摘要:Bulk MgB2 with SiO2 nanoparticles added has been synthesized using a simple solid-state reaction route. The lattice constant in the c direction increases with additive content due to a small amount of Si being doped into the lattice of the MgB2; however, T-c is almost fixed at 37.2 K. The addition Of SiO2 nanoparticles also improves the J(c)-H and H-irr-T characteristics of MgB2 when the additive content is lower than 7%. At 20 K and 1 T, J(c) for the sample with 7% additive content reaches 2.5 x 10(5) A cm(-2).
