Transformed material coefficients for single-domain 0.67Pb(Mg_(1/3)Nb_(2/3))O_(3)-0.33PbTiO_(3) single crystals under differently defined coordinate systems

摘要

Due to the confusion in choosing coordinate systems, there occurred some misrepresentations/calculations of effective material properties of 0.67Pb(Mg_(1/3)Nb_(2/3))O_(3)-0.33PbTiO_(3) single crystals based on its single-domain data. This letter is to clarify these confusions by providing proper data set for each of the currently used coordinate systems.
