Stoichiometry–anisotropy connections in epitaxial L10 FePt(001) films

Epitaxial L10 FePt films on SrTiO3 (1 0 0) by sputtering

FePt magnetic thin films (20 nm) were deposited on SrTiO3 (1 0 0) single-crystal substrates at 150, 250, and 350 1C by DC magnetron sputtering. The dependence of the structural and magnetic properties of the FePt films on the substrate temperature was studied. At 150 1C, the FePt film showed a (1 1 1) preferred orientation. At 250 1C, the superlattice FePt (0 0 1) peak appeared indicating that ...

Tuned Magnetic Properties of L10-MnGa/Co(001) Films by Epitaxial Strain

We demonstrate that the interface structure has a significant influence on the magnetic state of MnGa/Co films consisting of L1(0)-MnGa on face-centered-cubic Co(001) surface. We reveal an antiferromagnetic to ferromagnetic magnetization reversal as a function of the lateral lattice constant. The magnetization reversal mainly originates from localized states and weak hybridization at interface ...

Effect of lattice mismatch on chemical ordering of epitaxial L10 FePt films

The effect of lattice mismatch on the chemical ordering of epitaxial FePt films was studied. The results showed that the lattice constant scd of the FePt films decreased with increasing lattice mismatch « from about 2.23% to 6.33%. Upon further increase of « to about 8.8%, c increased. On the other hand, the variation of the lattice constant sad of the FePt films showed a reversal behavior to t...
