Characterizing Elasticity of NiTi Epitaxial Film in Austenitic Phase by Transient Grating Spectroscopy
Original language description
We employ transient grating spectroscopy (TGS) with a 7 μm excitation wavelength to analyze anisotropic elasticity of a thin supported film. The high sensitivity of TGS enables detection of multiple surface acoustic modes—Rayleigh, Sezawa (both with strong out-of-plane displacement), and Love (with transverse horizontal displacement)—in a slow-on-fast system of a 3μm thick epitaxial NiTi shape-memory alloy film on MgO, investigated in the austenitic state at 120 °C. Extracting elastic constants from angular dispersions is solved via the Ritz–Rayleigh method, enabling analysis of the cubic elastic constants of the NiTi film and provides valuable insights into the film’s properties.
