For mechanical spectroscopy measurements, a five elements piezoelectric device recently developed has been used. In addition, other characterization techniques as, differential thermal analysis and superconducting quantum interference magnetic spectroscopy, were also used. Besides, relaxation processes near the martensitic transition temperature have been also observed.11 p.application/pdfengCreative Commons Attribution 4.0 International (CC BY 4.0)NiMnSnFerromagnetic shape memory alloysComposite piezoelectric oscillatorShort and brittle samplesinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
