Crystal Oriented Manganese Zinc Ferrites Made from Acicular Fine Particles

The acicular Mn-Zn ferrite fine particles composed of 65.6 mol% Fe, 21.9 mol% Mn and 12.5 mol% Zn were made. These Mn-Zn femte particles were etched in IN-HC1 solution for 3hrs.. The fine particle was made up of several crystallites whose long axis were 0.2-1.0ptt1, and arranged to (31 1) direction. These fine particles were pressed with applying magnetic field. The oriented Mn-Zn ferrites were...

Auger Electron Spectroscopy of Free Argon Clusters

Auger electrm specm and Auger yields of free argon clusm in the I\I('Zp) excitation regime are reported. The Auger yield specua show chmcmistic changes as a function of cluster size. The results indicafe that the Auger yield signal originates primarily i%om the surface of the clusm. The results are compared to bulk-sensitive experimental techniques, such as tMal elecucm yields my), zero kinetic...

Surface Studied with Auger Electron Spectroscopy

We present an Auger electron spectroscopy (AES) study of the adsorption of nitric oxide (NO) on a dean Si(100)2 × 1 surface at 300 and 550 K. Accurate measurements reveal wall resolved fine structure at Auger Si L2.3 w transitions at 62 and 83 eV. These peaks can be attributed to Si-O and Si-N bonds. Furthermore, it is argued that the broadening in the SiLi2,~W Auger transition at 83 eV at 300 ...

Electrical Properties of Individual Zinc Oxide Grain Boundaries Determined by Spatially Resolved Tunneling Spectroscopy

Scanning tunneling microscopy (STM) and spatially resolved tunneling spectroscopy (TS) were used to observe correlations between the geometric structure and electrical properties of polycrystalline ZnO surfaces under ultrahigh vacuum. Constant current images revealed crystallographic features at a range of length scales, including facets which are hundreds of nanometers long and monoatomic step...
