Understanding the nature of competing phases is a key to understanding the superconducting mechanism of unconventional superconductors. Here, the authors demonstrate a three-dimensional charge ordering state which competes with superconductivity in epitaxial YBa2Cu3O7-x thin films grown on La0.7Ca0.3MnO3substrates.
