Description
Jayjit Kumar Dey and co-authors measure hidden tilts at an oxide interface and tie them to magnetism in a 2025 study. Perovskite oxides stack oxygen octahedra whose tilts steer electronic behavior. At a crafted junction of two such oxides, the team projected the oxygen angles directly, quantifying how substrate strain bends them.
A stretched substrate produced far stronger tilt than a squeezed one. X-ray probes then mapped how orbitals and magnetic coupling rearranged at the interface. Cobalt and manganese moments opposed each other across the seam. Computer theory matched the trend: stretch raised atomic moments, squeeze lowered them, with bond angles doing the steering. Single films of either oxide behaved differently from the pair. The authors present tilt measurement plus strain control as a knob for designing interface phenomena atom by atom.
