· MnAu

MnAu is an intermetallic compound combining manganese and gold, belonging to the family of binary metal alloys that exhibit ordered crystalline structures. This material is primarily investigated in research and materials science contexts for applications requiring a combination of magnetic properties (from manganese) and chemical stability (from gold), rather than as a widely commercialized engineering material. The MnAu system is of particular interest in magnetism research, magnetic recording technologies, and potentially in high-performance applications where corrosion resistance and specific magnetic behavior must be balanced.
