IGC Fabrication and TEM Characterization of Mn Nanoparticles (2009)
Li, Xingzhong, Sun, Zhiguang, Sellmyer, David J.
The reason for the enormous interest in nanomaterials is because they display unique and superior properties that are generally unavailable in conventional macroscopic materials. Gleiter and...
Proteresis in Co:CoO core-shell nanoclusters (2008)
Skomski, Ralph, Sun, Zhiguang, Sellmyer, David
The magnetism of ultrasmall Co:CoO core-shell nanoclusters is investigated. The structures, produced by cluster-beam deposition, have Co core sizes ranging from 1 to 7 nm and a CoO shell thickness of...
Cluster-Assembled Iron-Platinum Nanocomposite Permanent Magnets (2007)
Rui, Xiangxin, Sun, Zhiguang, Xu, Yinfan, Sellmyer, David J., Shield, Jeffrey E.
Exchange-spring nanocomposite permanent magnets have received a great deal of attention for their potential for improved the energy products. Predicted results, however, has been elusive. Optimal...
High-energy product exchange-spring FePt/Fe cluster nanocomposite permanent magnets (2006)
Rui, X., Shield, Jeffrey E., Sun, Zhiguang, Yue, L., Xu, Yinfan, Sellmyer, David J., ...
In this paper, we report on the production of Fe cluster/FePt matrix nanocomposite permanent magnets. Monodispersed Fe clusters with sizes below 10 nm were formed by gas aggregation techniques. These...
In-cluster-structured exchange-coupled magnets with high energy densities (2006)
Rui, X., Shield, Jeffrey E., Sun, Zhiguang, Xu, Yinfan, Sellmyer, David J.
In this letter, the authors demonstrate isotropic Fe-Pt exchange-spring nanocomposite permanent magnets with a soft magnetic phase fraction of greater than 0.5 with a coercivity of 6.5 kOe,...
Cluster-assembled exchange-spring nanocomposite permanent magnets (2005)
Rui, X., Sun, Zhiguang, Xu, Yinfan, Sellmyer, David J., Shield, Jeffrey E.
Isotropic nanocomposite magnetic structures were produced via cluster assembly routes with energy products reaching 18 MG Oe. Gas aggregation produces Fe clusters with an average size less than 10 nm...
Magnetic properties of L10 FePt and FePt:Ag nanocluster films (2003)
Xu, Yinfan, Sun, Zhiguang, Qiang, Y., Sellmyer, David J.
A sputtering gas-aggregation technique has been used to prepare FePt and FePt:Ag nanocluster films. The cluster size was controlled in a range from 3 to 6 nm. FePt cluster films were directly...
Korenberg, Julie R., Chen, Xiao-Ning, Sun, Zhiguang, Shi, Zheng-Yang, Ma, Shaowu, Vataru, Eddy, ...
Human genome sequencing is accelerating rapidly. Multiple genome maps link this sequence to problems in biology and clinical medicine. Because each map represents a different aspect of the structure,...
