Linking Centered Manganese Triangles into Larger Clusters:A {Mn_(32)} Truncated Cube

摘要

Single-molecule magnets(SMMs)have many potential applications including high-density information storage,in which each bit of information is stored as the magnetization orientation of an individual molecule,and as qubits for quantum computation,in which the required arbitrary superposition of quantum states with opposite projections of spin can be produced by either quantum tunneling of the magnetization,intermolecular exchange,or multifrequency EPR pulses.The fundamental requirements for a molecule to behave as an SMM are a)a relatively large spin ground state(S)and b)a large and negative zero-field splitting(zfs)of that ground state(as measured by the zfs parameter D).
