Magnetic structure of the emerging spin density wave phase in Nb1-yFe2+y
Our previous neutron scattering of ferromagnetic (FM) Nb1-yFe2+y revealed that chemical composition (y) tuning leads to a FM quantum-critical point masked by an emerging spin-density wave (SDW). The latter could be connected to many exciting phenomena, including field-induced quantum-critical lines, quantum tri-critical points, and quantum multi-critical points. Our previous neutron scattering experiments revealed the SDW ordering wave vector, but here we propose a dedicated magnetic neutron diffraction experiment to reveal the detailed magnetic structure, which might resemble a modulation of a ferrimagnetic building block. The results would form an important test for, e.g., order-by-disorder models that predict the emergence of modulated order at the border of ferromagnetism. Here, we apply for 7 days of beamtime at D10.
