Energy-Filtered Tem of Ag-Co Thin Films
Published online by Cambridge University Press: 15 February 2011
Abstract
TEM grids containing Ag65Co35 thin films were annealed under protocols corresponding to maximum giant magnetoresistance (GMR) response in thicker films. These films were examined using high resolution TEM, electron energy loss spectroscopy (EELS), and electron spectroscopic imaging (ESI), which revealed small (50 nm diameter) Ag particles and very small (approximately 2 nm diameter) clusters in a suspending matrix of Ag-Co alloy. Cobalt maps did not reveal individual cobalt clusters, indicating that if such clusters exist, they are smaller than the 1–2 nm resolution limit of the technique.
