Ultrathin nanosheets of Mn3O4: A new two-dimensional ferromagnetic material with strong magnetocrystalline anisotropy

         

摘要

Two-dimensional (2D) materials with robust ferromagnetism have played a key role in realizing next-generation spin-electronic devices,but many challenges remain,especially the lack of intrinsic ferromagnetic behavior in almost all 2D materials.Here,we highlight ultrathin Mn3O4 nanosheets as a new 2D ferromagnetic material with strong magnetocrystalline anisotropy.Magnetic measurements along the in-plane and out-of-plane directions confirm that the out-of-plane direction is the easy axis.The 2D-confined environment and Rashba-type spin-orbit coupling are thought to be responsible for the magnetocrystalline anisotropy.The robust ferromagnetism in 2D Mn3O4 nanosheets with magnetocrystalline anisotropy not only paves a new way for realizing the intrinsic ferromagnetic behavior in 2D materials but also provides a novel candidate for building next-generation spin-electronic devices.
