| Research Abstract |
A new class of superparamagnetism was found in relaxor ferroelectrics having magnetic ions 2/3BiFeO_3-1/3BaTiO_3. The polar nanoregion (PNR), which governs the relaxor ferroelectric property, affects the magnetic ordering significantly, and the resulting magnetic nano-domains are the new origin of superparamagnetism. The superparamagnetism induced by PNR is very unique because of its inherent connection between dielectric and magnetic properties.
