  The 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 oC. 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.
