| Abstract: | Structures and magnetic properties of transition metal(TM) Fe or Ni monoatomic chains(MACs) encapsulated by a Au(5,5) nanotube(Fe@Au and Ni@Au) are investigated using the density functional theory(DFT).The calculated results show that both Fe@Au and Ni@Au prefer to adopt ferromagnetic(FM) orders as ground states.In particular,the Fe@Au keeps the magnetic properties of free-standing Fe MAC,indicating that this system may be viewed as a new candidate in electromagnetic devices. |
