稀土单分子磁体研究进展

Single-molecule magnets (SMMs) are a class of nano-scale magnetic materials, and have attracted much attention due to the potential applications in high-density information storage, quantum qubits and molecular spintronic devices. Owing to the large magnetic moment and strong magnetic anisotropy, some rare-earth ions have incomparable advantages over transition metal ions in the construction of high-performance SMMs. In this review, the recent progress in rare earth SMMs represented by mononuclear and dinuclear complexes were high lighted, especially for the break through of the magnetic blocking temperature over the boiling point temperature of liquid nitrogen (77 K), which lays a solid foundation for futuristic single-molecule information storage at room temperature.
