Study of Field-Induced Magnetization in a New Iron-Based Superconductor Using Polarized Neutron Diffraction
Ferromagnetic and antiferromagnetic spin fluctuations tend to mediate superconducting pairing with different symmetry. In contrast to the widely-studied AFM fluctuations, FM fluctuations are largely unexplored due to the limited candidate compounds. Recently, our inelastic neutron scattering measurements have observed the coexistence of in-plane FM and stripe-type AFM spin fluctuations in a newly-synthesized iron germanium superconductor YFe2Ge2. The FM spin fluctuations were found to be stronger in the low energy regime, suggesting the possibility of unconventional pairing mechanism. The field-induced magnetization measurement using polarized neutron diffraction has been adopted to probe the pairing symmetry in many superconductors, including cuprates, iron pnictides and Sr2RuO4. On purpose of revealing the SC ground state in YFe2Ge2, we thereby plan to extract the field-induced magnetization and track its temperature dependence across Tc in our high-quality, bulk-superconducting sample. The success of the experiment will provide crucial information on the pairing symmetry in YFe2Ge2.
