 | Liu, Feng | Effect of size and dimensionality on the magnetic moment of transition metals | The effect of size and dimensionality on the magnetic moments of Fe, Co, and Ni have been studied theoretically by confining the atoms t o various structural forms such as chains,surfaces, and thin films. The size of these systems is controlled by limiting t h e number of atoms. A new first-princip... | Magnetic moment; Dimensionality; Size effects; Fe; Co; Ni | 1990 |

 | Gondolo, Paolo | Implications of muon anomalous magnetic moment for supersymmetric dark matter | The anomalous magnetic moment of the muon has recently been measured to be in conflict with the standard model prediction with an excess of 2.6s. Taking the excess at face value as a measurement of the supersymmetric contribution, we find that at 95% confidence level it imposes an upper bound of 50... | Magnetic moment; Neutralinos | 2001-05 |

 | Gondolo, Paolo | Improved constraints on supersymmetric dark matter from muon g-2 | The new measurement of the anomalous magnetic moment of the muon by the Brookhaven AGS experiment 821 again shows a discrepancy with the standard model value. We investigate the consequences of these new data for neutralino dark matter, updating and extending our previous work [E. A. Baltz and P. ... | Magnetic moment; Neutralinos | 2003-03 |

 | Liu, Feng | Magnetism and local order II: self-consistent cluster calculations | The effect of the local environment on the magnetic moment and its convergence to bulk value has been studied self-consistently by using a molecular-cluster model within the framework of spin-density-functional theory. We show that the magnetic moment of the central atom in clusters of 43 Ni atoms a... | Local order; Magnetic moment; Molecular-cluster model; Spin-density-functional theory | 1989-07 |

 | Liu, Feng | Magnetism and local order: ab initio tight-binding theory | The effects of the local environment on the electronic structure and magnetic moments of Fe, Co, and Ni have been studied by confining these atoms to assume various structural forms such as chains, surfaces, layers, and crystals. The coordination number of the atoms can thus be changed over a wide r... | Local order; Ab-initio tight-binding theory; Magnetic moment; Electronic structure; Fe; Co; Ni | 1989-04 |

 | Liu, Feng | Simple theory of the electronic structure: clusters to crystals | A simple scheme based upon a cross between the molecular clusters and the tight-binding theory has been developed to calculate the electronic structure of a large class of systems ranging from molecules to solids. The method is applied to study the variations in the magnetic moments of Fe and Ni for... | Clusters; Tight-binding theory; Magnetic moment | 1988-09 |
