Interlayer Coupling of Iron Films Across Chromium Interlayers and Its Relation to Growth and Structure

To investigate the exchange coupling of iron films across chromium interlayers Fe/Cr/Fe structures with good epitaxy and crystallinity have been grown, which is documented by in situ SPALEED and ex situ RBS investigations. For samples deposited at substrate temperature T sub s = 293K, the coupling o...

Description
Summary:To investigate the exchange coupling of iron films across chromium interlayers Fe/Cr/Fe structures with good epitaxy and crystallinity have been grown, which is documented by in situ SPALEED and ex situ RBS investigations. For samples deposited at substrate temperature T sub s = 293K, the coupling oscillates as a function of the interlayer thickness with a period of approx 1.8 nm. For samples made at T sub s = 523K, there is, in addition, a short period oscillation with a period of 2 ML and an appreciable contribution of 90 deg type coupling. The temperature dependence of the oscillations has been investigated.
