Towards an Unambiguous Electron Magnetic Chiral Dichroism (EMCD) Measurement in a Transmission Electron Microscope (TEM)
The intention of the ChiralTEM project (2004-2007) was the detection of electron (energy loss) magnetic chiral dichroism in a transmission electron microscope (TEM), in analogy to X-ray magnetic circular dichroism (XMCD). For the experiments, single-crystal electron transparent specimen's with magnetic induction perpendicular to the specimen's plane are required. In this thesis, different preparation techniques are evaluated regarding their usability to produce ideal specimen's for a verification of EMCD. After the demonstration of a dichroic measurement, an obvious way to prove the chiral effect is to invert the specimen's magnetization from parallel to antiparallel to the electron beam tra...
