    The emergence of nanoscale features — such as magnetic and electronic patterns — in materials that are otherwise homogeneous provides a potential alternative to conventional top-down and bottom-up fabrication techniques. The way these features arise in manganite crystals is contentious, but could be explained using elasticity theory.
