Lorentz Electron Microscopy of Magnetic Domains in Eptaxial Iron Films

Abstract

This paper describes the results of a study of domain walls in single crystal iron films by Lorentz electron microscopy. The films were prepared by evaporating 99.99% iron wire onto an air cleaved (100) rock salt substrate heated to 400°C. The films were stripped from the rock salt, mounted on Cu folding grids and annealed at a temperature between 700°C and 900°C. The study was performed in a Siemens Elmiskop 1 A operated in the weak field objective lens mode with the specimen raised 5.4 mm. above its normal operating position.
