【 摘 要 】

The development of spintronics (the field of science that examines the behavior of systems, based not only on charge transfer, but on magnetic properties of nano-objects as well) requires study of various magnetic and electrical properties of nanoscale systems. To create a new device it is often important to know a length of spin relaxation not only for electrons with energies close to the Fermi surface, but also with energy of several hundred eV. In this study we measured such lengths in palladium at room temperature. Results obtained by secondary electron spectroscopy show that spin relaxation length for energy 100 eV is 11,91,6Å and for energy 500 eV is 27,110,5Å.
