⚛️ New research on cuprate superconductors spotted
Scientists analyzed the bulk microstructure of La1.675Eu0.2Sr0.125CuO4 using scanning three-dimensional X-ray diffraction. They discovered broad tetragonal-like domain wall regions within the crystal structure. Further cooling the sample to 100 K revealed fine orthorhombic-like stripes inside the tetragonal matrix. This finding impacts how the structural and electronic heterogeneity in these materials is understood. The study validates 3DXRD as a strong method for studying bulk material microstructures.
