title = "Coexistence of ferromagnetism and superconductivity in CeO0.3 F0.7BiS2",
abstract = "Bulk magnetization, transport, and neutron scattering measurements were performed to investigate the electronic and magnetic properties of a polycrystalline sample of the newly discovered ferromagnetic superconductor, CeO0.3F0.7BiS2. Ferromagnetism develops below TFM=6.54(8)K and superconductivity is found to coexist with the ferromagnetic state below TSC∼4.5K. Inelastic neutron scattering measurements reveal a very weakly dispersive magnetic excitation at 1.8 meV that can be explained by an Ising-like spin Hamiltonian. Under application of an external magnetic field, the direction of the magnetic moment changes from the c axis to the ab plane and the 1.8 meV excitation splits into two modes. A possible mechanism for the unusual magnetism and its relation to superconductivity is discussed.",
