Summary: The intermetallic compounds formed between gold and manganese possess a range of magnetic properties. In particular some are antiferromagnetic to unsually high temperatures. Unfortunately the phase relationships are not well known and the current binary phase diagram is uncertain in the important region lying between the compounds AuMn and AuMn2. In the present project we will apply X-ray diffraction at temperatures up to 800 °C to powder samples to elucidate the stability, structures, and interrelationships of the various high temperature phases. This new knowledge will open the way for an exploration of the systematic exploration of their magnetic properties.
