Magnetism of nanocrystalline (La(0.5)Sr(0.5))TiO3 doped with 3d cations.

Nanocrystallites of nominal composition (La(0.5)Sr(0.5))TiO(3) 12-15 nm in diameter exhibit a diamagnetic susceptibility that is greater by a factor of three than that of bulk ceramic material, due to a much-reduced Pauli paramagnetic contribution associated with oxidation (cation deficiency) of the material.
