Fabrication of high quality plan-view TEM specimens using the focused ion beam

We describe a technique using a focused ion beam instrument to fabricate high quality plan-view specimens for transmission electron microscopy studies. The technique is simple, site-specific and is capable of fabricating multiple large, >100 μm2 electron transparent windows within epitaxially-grown thin films. A film of La0.67Sr0.33MnO3 is used to demonstrate the technique and its structural and functional properties are surveyed by high resolution imaging, electron spectroscopy, atomic force microscopy and Lorentz electron microscopy. The window is demonstrated to have good thickness uniformity and a low defect density that does not impair the film’s Curie temperature. The technique will enable the study of in–plane structural and functional properties of a variety of epitaxial thin film systems

CURRENCY MARKET CONTAGION IN THE ASIA-PACIFIC REGION

During the East Asian currency crisis of 1997-98 the potential transmission of the crisis to developed markets such as Japan, Australia and New Zealand, was of considerable policy concern. Potential channels consist of anticipated movements stemming from common factors, spillovers and contagion. The empirical results show that the transmission of volatility in the East-Asian currency markets to the developed markets in the region is not due to contagion, but rather attributed to common world factors. Spillovers have a minor role in the case of Japan and to a lesser degree, Australia. Copyright Blackwell Publishing Ltd/University of Adelaide and Flinders University of South Australia 2004.
