From: Nonvolatile modulation of electronic structure and correlative magnetism of L10-FePt films using significant strain induced by shape memory substrates

Figure 2

Microstructure and strain evolution in L10-FePt(10 nm) films grown on shape memory alloy substrates with different amount of pre-deformation.

(a) XRD patterns of the samples with different macro-strain (εM) in the SMA substrates. (b)Variations of the FePt(111) d-spacing and the in-plane compressive lattice strain (εL) with εM. Cross-sectional HRTEM images of the samples: (c,d) εM = 0%; (e,f) εM = −3.5%. (g–k) Elemental mapping obtained from EDX scan of the area marked by the red square in Fig. 2f.
