Abstract

In this report, we have investigated the local coordination of strontium and calcium in Sr_1-xCa_xFeO₂ (x = 0, 0.8 and 1) via extended x-ray absorption fine structure at room temperature. We observe the different local coordinations in the infinite layer phases (x = 0, 0.8) and distorted infinite layer structure CaFeO₂.
