A team of CEM researchers including Profs. Fengyuan Yang, Pat Woodward, David McComb, Hamish Fraser, & Patricia Morris, as well as student and staff researchers Jeremy Lucy, Adam Hauser, Hailong Wang, Jenni Soliz, Manisha Dixit, and R. Williams have published an article in Applied Physics Letters titled, “Buffer-layer enhanced structural and electronic quality in ferrimagnetic Sr2CrReO6 epitaxial films.”
The article describes how the structural and electronic qualities in Sr2CrReO6 epitaxial films were enhanced through the minimization of defect states, particularly at the substrate – film interface. Minimization of the defect states was achieved through epitaxial growth of the Sr2CrReO6 double perovskite on an insulating and non-magnetic double perovskite buffer layer, Sr2CrNbO6. Crystalline quality and Cr/Re ordering in this material are crucial for intrinsic behavior such as semiconductivity at room temperature.
