Ferromagnetic order beyond the superconducting dome in a cuprate superconductor
Abstract
The phase diagram of cuprate superconductors, in addition to superconductivity, contains many ordered states such as antiferromagnetism, charge density waves, and nematicity. Sarkar et al. show that ferromagnetism should be added to this list. Studying thin films of La 2− x Ce x CuO 4 at high dopings, past the point at which superconductivity disappears, the researchers found signatures of ferromagnetism in both the transport and optical properties of the films.
