Magnetic Microstructure of the (0001) Surface of the HCP Cobalt

January 1, 1989
Author(s)
john unguris, M Scheinfein, Robert Celotta, Daniel T. Pierce
The magnetic domain structure of the (0001) surface of a hcp cobalt crystal was investigated using scanning electron microscopy with polarization analysis (SEMPA). This is the first observation by SEMPA of both out-of-plane and in-plane magnetization

Metallicity and Gap States in Tunneling to Fe Clusters on GaAs(110)

January 1, 1989
Author(s)
P First, Joseph Stroscio, Robert A. Dragoset, Daniel T. Pierce, Robert Celotta
We report the characteristics of tunneling to a GaAs(110) substrate with distinct, nanometer-size Fe clusters, as a function of distance from and size of the clusters. We show that Fe clusters of volumes 150 Aring} 3, corresponding to =13 atoms, are

Modeling Dynamic Surfaces with Octrees

January 1, 1989
Author(s)
Don E. Libes
Past users of octrees have been for representation of static objects. We discuss extensions necessary to model dynamic surfaces. One particularly important aspect of this is the ability to represent expanding surfaces that grow to be arbitrarily large. Que
