In-Situ Observation of Magneto-Optical Kerr Effect and Resistance of Fe Island Films

The magnetooptic Kerr effect and electric resistance of Fe deposited on fused quartz substrates were observed during ultra-high vacuum deposition. Resistance measurements show that Fe forms islands on the quartz substrates, and that films with such an island morphology turn into continuous films at about 115 Å thickness at room temperature. The magnetooptic Kerr effect is observable from a thickness of 16 Å, and a remanence magnetization appears from 21 Å.
