We describe the creation of a long-lived spin-orbit-coupled gas of quantumdegenerate atoms using the most magnetic fermionic element, dysprosium.Spin-orbit-coupling arises from a synthetic gauge field created by theadiabatic following of degenerate dressed states comprised of optically coupledcomponents of an atomic spin. Because of dysprosium's large electronic orbitalangular momentum and large magnetic moment, the lifetime of the gas is limitednot by spontaneous emission from the light-matter coupling, as for gases ofalkali-metal atoms, but by dipolar relaxation of the spin. This relaxation issuppressed at large magnetic fields due to Fermi statistics. We observelifetimes up to 400 ms, which exceeds that of spin-orbit-coupled fermionicalkali atoms by a factor of 10-100, and is close to the value obtained from atheoretical model. Elastic dipolar interactions are also observed to influencethe Rabi evolution of the spin, revealing an interacting fermionic system. Thelong lifetime of this weakly interacting spin-orbit-coupled degenerate Fermigas will facilitate the study of quantum many-body phenomena manifest at longertimescales, with exciting implications for the exploration of exotictopological quantum liquids.
