DOI: 10.1016/j.jmmm.2021.168406
Abstract: Abstract Magnetic anomalies in antiphase boundaries (APBs), which are a type of planar defect produced in ordered crystals, have been studied using electron holography. For many ordered crystals, including a Ni50Mn25Al12.5Ga12.5 alloy with a Heusler-type… read more here.
