Magnetic thin films are proposed for a range of spintronic and other applications. While exploring so-called magnetic “dead layers” in La0.7Sr0.3MnO3 thin films, we detect a magnetic phase competition between two types of magnetic order. This competition leads to spontaneous magnetization reversal, which had not previously been observed in epitaxial thin films. This effect allows switching the magnetization direction with very small applied magnetic fields, which could significantly benefit spintronic and other applications.
