High quality cubic Tb-doped magnetite nanocrystals have been fabricated and have shown that the Tb is incorporated into the octahedral 3+ sites. Magnetization and FMR data indicate that the Tb spins are weakly coupled to the iron spin lattice at room temperature. These Tb-doped nanoagents, which have a large saturated moment, a large fluctuating moment, and a luminescent component, may provide unique magnetic resonance and optical imaging signatures.
