Magnetic Order and Its Interplay with Structure Phase Transition in van der Waals Ferromagnet VI_(3)

         

摘要

Van der Waals magnet VI_(3) demonstrates intriguing magnetic properties that render it great for use in various applications.However,its microscopic magnetic structure has not been determined yet.Here,we report neutron diffraction and susceptibility measurements in VI_(3) that revealed a ferromagnetic order with the moment direction tilted from the c-axis by ~36° at 4 K.A spin reorientation accompanied by a structure distortion within the honeycomb plane is observed,before the magnetic order completely disappears at TC=50 K.The refined magnetic moment of ~1.3μB at 4 K is much lower than the fully ordered spin moment of 2μB/V^(3+),suggesting the presence of a considerable orbital moment antiparallel to the spin moment and strong spin-orbit coupling in VI_(3).This results in strong magnetoelastic interactions that make the magnetic properties of VI_(3) easily tunable via strain and pressure.
