Spin Nomenclature for Semiconductors and Magnetic Metals
No s prop The different conventions used in the semiconductor and magnetic metals communities can cause confusion in the context of spin polarization and transport in simple heterostructures. In semiconductors, terminology is based on the orientation of the electron spin, while in magnetic metals it is based on the orientation of the moment. In the rapidly expanding field of spintronics, where ...
متن کاملThe magnetic polarity stratigraphy of the Mauch Chunk Formation, Pennsylvania.
Three sections of Chesterian Mauch Chunk Formation in Pennsylvania have been studied paleomagnetically to determine a Late Mississippian magnetic polarity stratigraphy. The upper section at Lavelle includes a conglomerate with abundant red siltstone rip-up clasts that yielded a positive conglomerate test. All samples were subjected to progressive thermal demagnetization to temperatures as high ...
متن کاملStratigraphy in Phylogeny Reconstruction
Beginning with this issue, the Journal of Paleontology will be publishing an occasional section entitled ‘‘View from the Field’’. ‘‘View from the Field’’ will provide a forum for concise commentary on current issues in paleontology, including but not limited to discussion of methods, important new discoveries, and major conceptual advances. Contributions should be brief (no more than 12 double-...
متن کاملSequence Stratigraphy
Sequence stratigraphy is the study of sediments and sedimentary rocks in terms of repetitively arranged facies and associated stratal geometry (Vail 1987; Van Wagoner et al 1988, 1990; Christie-Blick 1991). It is a technique that can be traced back to the work of Sloss et al (1949), Sloss (1950, 1963), and Wheeler (1958) on interregional unconformities of the North American craton, but it becam...
