The proposed HARFIR project intends to develop antiferromagnetic (AF) Heusler alloy (HA) films to replace the antiferromagnetic alloy Iridium Manganese (IrMn), which has been widely used in all spin electronic devices including hard disk drives and next-generation magnetic memories. Accordingly the price of Ir has risen by a factor of 4 in the last five years and by more than a factor of 10 in the ...
