In a recent report, Chivani et al explored the mechanical properties of more than 13K materials, After collecting the elastic tensor data from Materials Project, properties like shear modulus, bulk modulus, Young's modulus, Poisson's ratio, and linear compressibility have been calculated using Elate software developed by the same group. They reported 121 auxetic materials(average Poisson's ratio is negative) out of 11764 materials but only 75 materials out of them are stable. Only stable auxetic materials are used in this study. All the necessary descriptors of these materials have been gathered from the ever-reliable Material Project. The data cleaning process is described in the result section.
