| 英文摘要 | A series of Sr(Co1-xNix)(2)As-2 single crystals was synthesized, allowing a comprehensive phase diagram with respect to field, temperature, and chemical substitution to be established. Our neutron diffraction experiments revealed a helimagnetic order with magnetic moments ferromagnetically aligned in the ab plane and a helimagnetic wave vector of q = (0, 0, 0.56) for x = 0.1. The combination of neutron diffraction and angle-resolved photoemission spectroscopy measurements shows that the tuning of a flat band with d(x2-y2) orbital character drives the helimagnetism and indicates the possibility of a quantum order-by-disorder mechanism. |
