Chemical Aspects of Tool Wear in Single Point Diamond Turning

Author(s)
E W. Paul, Christopher J. Evans, A Mangamelli, Michael L. McGlauflin, Robert S. Polvani
A hypothesis is proposed that ascribes chemical wear of diamond tools to the presence of unpaired d electrons in the sample being machined. This hypothesis is

Generation of Non-Classical Motional States of a Trapped Atom

Author(s)
D M. Meekhof, C Monroe, B E. King, Wayne M. Itano, David J. Wineland
We report the creation of thermal, Fock, coherent, and squeezed states of motion of a harmonically bound 9Be+ ion. The last three states are coherently prepared

A Schrödinger Cat" Superposition State of an Atom

Author(s)
C Monroe, D M. Meekhof, B E. King, David J. Wineland
A "Schrödinger cat"-like state of matter was generated at the single atom level. A trapped 9Be+ ion was laser-cooled to the zero-point energy and then prepared

Laser focusing of atoms for nanostructure fabrication

Author(s)
J Mcclelland, Robert Celotta, Zeina J. Kubarych, R Gupta
Laser focusing of atoms has emerged as a viable form of nanofabrication. Structures are formed by focusing chromium atoms as they deposit onto a surface. The

Microstrucutral Effects in Precision Hard Turning

Author(s)
Y K. Chou, Christopher J. Evans
Precision hard turning provides an alternative to grinding in some finishing applications. Rapid tool wear, however, remains a bottleneck to the process being

Optimizing the GMR of Symmetric and Bottom Spin Valves

Author(s)
William F. Egelhoff Jr., P J. Chen, Cedric J. Powell, Mark D. Stiles, Robert McMichael, C Lin, J Sivertsen, J Judy, K Takano, A Berkowitz, T Anthony, J Brug
We have attempted to optimize the values of the giant magnetoresistance in symmetric spin valves of the type NiO/Co/Cu/Co/Cu/Co/NiO (achieving 23.4%) and in

Low-temperature Growth of GMR Spin Valves

Author(s)
William F. Egelhoff Jr., R Misra, T Ha, Y Kadmon, Cedric J. Powell, Mark D. Stiles, Robert McMichael, Lawrence H. Bennett, C Lin, J Sivertsen, J Judy
We have investigated the dependence of the giant magnetoresistance (GMR) effect, the coercivity, the coupling field, and the resistivity on film deposition at

The Trade-off Between Large GMR and Small Coercivity in Symmetric Spin Valves

Author(s)
William F. Egelhoff Jr., P J. Chen, Cedric J. Powell, Mark D. Stiles, Robert McMichael, C Lin, J Sivertsen, J Judy, K Takano, A Berkowitz
We have investigated the use of various alloys as substitutes for pure Co in the center film of symmetric spin valves of the type NiO/Co/Cu/Co/Cu/Co/NiO. The

Growth of GMR Spin Valves using Indium as a Surfactant

Author(s)
William F. Egelhoff Jr., P J. Chen, Cedric J. Powell, Mark D. Stiles, Robert McMichael
We have investigated the use of In as a surfactant to achieve smoother interfaces in spin-valve multilayers of the general type: FeMn/Ni 80Fe 20/Co/Cu/Co/Ni

Growth of Giant Magnetoresistance Spin Valves Using Pb and Au as Surfactants

Author(s)
William F. Egelhoff Jr., P J. Chen, Cedric J. Powell, Mark D. Stiles, Robert McMichael, C Lin, J Sivertsen, J Judy, K Takano, A Berkowitz
We have investigated the use of Pb and Au as surfactants in an attempt to achieve smoother and sharper interfaces in three types of giant magnetoresistance (GMR
