Nanomechanics of multiferroic composite nanofibers via local excitation piezoresponse force microscopy

Mechanical properties of multiferroic nanostructures are of great importance for their applications, yet their characterization is challenging, especially in a quantitative manner and simultaneously with their piezoelectric properties. In this paper, we show that the widely applied piezoresponse force microscopy, when appropriately carried out and analyzed, can be utilized to quantitatively map the Young's modulus of multiferroic nanofibers with...
