antiferromagnetic to ferromagnetic transition occurring above
room temperature in FeRh is attracting interest for applications in
spintronics, with perspectives for robust and untraceable data storage.
Here, we show that FeRh films can be grown on a flexible metallic
substrate (tape shaped), coated with a textured rock-salt MgO layer,
suitable for large-scale applications. The FeRh tape displays a sharp
antiferromagnetic to ferromagnetic transition at about 90 °C.
Its magnetic properties are preserved by bending (radii of 300 mm),
and their anisotropic magnetoresistance (up to 0.05%) is used to illustrate
data writing/reading capability.
