Mechanical and magnetic properties of Mn-Pt compounds and nanocomposites
Original language description
An analysis of mechanical and magnetic properties of Mn-Pt compounds and nanocomposites is provided using DFT calculations. Adding manganese to platinum matrix reduces the bulk modulus and enhances the Young moduli and shear moduli. With increasing Mn content, the theoretical tensile strength is also enhanced and the corresponding maximum deformation is reduced. On the whole, manganese addition makes the Mn-Pt compounds softer, but increases their resistance to shape deformation. Many of these compoundsmay be considered as natural linear nanocomposites. We studied the magnetic configurations of recently found MnPt7 ordered structure and predict an antiferromagnetic state with spins altering along the [100] direction to be the ground state of this compound. The ferromagnetic state and an alternative antiferromagnetic state with spins altering along the [111] direction have a higher total energy. We further studied Mn-Pt nanocomposites exhibiting the composition of MnPt15. The preferent
