Description:
Author(s): A. Rebello, J. J. Neumeier, Zhaoshun Gao, Yanpeng Qi, and Yanwei Ma Lanthanum doping for calcium in CaFe 2 As 2 results in negative thermal expansion that can be exceptionally large. The behavior is unusual among Fe-As materials, and is presumably associated with the close proximity of CaFe 2 As 2 to a structural phase instability. [Phys. Rev.
