“…342 The formation of nanostructures (including ferromagnetic ones) in MnAs films (T C = 310 K) deposited on GaAs(001) substrate was observed at 30 °C. 343 Unstable compounds CrAs 209, 344 and CrSb 345 with the zinc blende structure were prepared by deposition on GaAs substrates. These materials possess room temperature ferromagnetism.…”

The review concerns the fundamentals of spintronics (spin transport electronics). The material covers spin spin interactions and spin relaxation in semiconductors as well as spin and spin injection related effects in the condensed matter. Examples of promising spintronic de vices are given, requirements for spintronic materials are formulated, methods of synthesis of spintronic materials are described, and the physicochemical properties of some materials are characterized. Organic spintronic materials are briefly outlined and the state of the art in the field of research on inhomogeneous magnetic semiconducting materials possessing high tem perature ferromagnetism is described. The emphasis is placed on the chemical bonding and electronic structure of magnetic impurities in semiconductors, consideration of the nature of ferromagnetism, and on the character of exchange interactions between localized spins in novel spintronic materials.

“…They have been realized using Si [1], Ge [2][3][4], GaAs, GaP and GaSb [5]. For example, naturally available silicon ( nat Si) is composed of three stable isotopes in fixed proportion ( 28 Si: 92.2 at.%, 29 Si: 4.7 at.%, 30 Si: 3.1 at.%).…”

“…With the isotope SLs, we expect to observe characteristic phonon frequencies which appear due to confinement longitudinal optical (LO) phonons in specific isotope layers [1][2][3][4][5]. Comparison of such peaks with calculation assuming appropriate number of monolayer (ML) n and degree of interface intermixing l will allow for determination of n and l in each superlattice.…”
