| 288 | The Dipole-Octupole Quantum Spin Ice Candidate Ce2Zr2O7 Related Papers Related Patents Related Grants Related Venues Related Experts View Highlight: Muon spin relaxation measurements on single crystal Ce 2Zr 2O 7 show a lack of both magnetic order and spin freezing down to T = 0.02 K. Furthermore, low-energy inelastic neutron scattering measurements at low temperature show a lack of magnetic order and a snowflake-like pattern of diffuse scattering that is characteristic of quantum spin ice. No obvious spin waves are observed in the low-energy excitation spectrum of Ce 2Zr 2O 7, in both zero and non-zero magnetic field, and this eliminates the most common method of estimating the microscopic spin Hamiltonian by fitting spin wave dispersions using linear spin wave theory. |
