Bending strain-tunable magnetic anisotropy in Co2FeAl Heusler thin film on Kapton
Bending effect on the magnetic anisotropy in 20 nm CoFeAl Heusler thin
film grown on Kapton\textregistered{} has been studied by ferromagnetic
resonance and glued on curved sample carrier with various radii. The results
reported in this letter show that the magnetic anisotropy is drastically
changed in this system by bending the thin films. This effect is attributed to
the interfacial strain transmission from the substrate to the film and to the
magnetoelastic behavior of the CoFeAl film. Moreover two approaches to
determine the in-plane magnetostriction coefficient of the film, leading to a
value that is close to , have been proposed.Comment: 4 pages, 4 figure
