ABSTRACT
Ultrasonic irradiation of magnesium diboride slurries in decalin produces material with significant intergrain fusion. Sonication in the presence of Fe(CO)[sub 5] produces magnetic Fe[sub 2]O[sub 3] nanoparticles embedded in the MgB[sub 2] bulk. The resulting superconductor–ferromagnet composite exhibits considerable enhancement of its magnetic hysteresis, which implies an increase of vortex pinning strength due to embedded magnetic nanoparticles. © 2003 American Institute of Physics.
