Abstract

• Mn₂FeSn is a Heusler alloy with a hexagonal crystal structure and tunable magnetic properties.
• Exchange Bias (EB) effect is a magnetic effect of ferromagnetic (FM) materials that are coupled to antiferromagnetic (AFM) materials.
• Coercivity or the coercive field is the opposing magnetic field required to reduce a magnetic material’s magnetization to zero.
• Field-cooled (FC) samples are heated to a high temperature and then cooled in the presence of an applied magnetic field, allowing the magnetic spins to align with the field and retain this orientation.
• Zero field cooled (ZFC) samples are not cooled in a field when measured.
• Relevant for magnetic memory and spintronic devices.
