Magnetic properties of epitaxial Fe(Si1−xFex) films grown on Si(111)

Phase transformation in FeSi2 nanowires

“…This phase was predicted to exist and to be ferromagnetic, based on band-structure calculations [6]. s-FeSi 2 has a CsCl lattice and is metallic and non-magnetic [17]. A magnetic behavior of cubic-FeS 2 NWs was recently reported with 0.3 Bohr magneton per iron atom at 2 K [18].…”

Structural and magnetic properties of cobalt nanostructures on SiO 2 /Si(1 1 1) substrates

“…Co nanoplatelets with uniform size, height and shape were fabricated by ultrahigh vacuum metal evaporation on the Si(1 1 1)-(7 × 7) surface, using a two-dimensional identical Al cluster array as the template and spacer [16]. In fact, the Si (1 1 1) surface is known to be very reactive, with metal [13,[16][17][18][19][20] or gas [21,22] due to its fascinating temperature-dependant surface reconstructions exhibiting various and numerous dangling bonds, adatoms or stacking-faults. In this paper, we present the structural and magnetic properties of 2D architectures of cobalt on native Si (1 1 1) oxidized surfaces elaborated using lithography-free synthesis and patterning of magnetic cobalt in the nanometer scale.…”

“…Chérif). moment of iron atoms in iron silicides depends on the chemical composition of iron silicides [13]. In order to avoid such effects, a buffer between the silicon and the magnetic metal is used to prevent the formation of a silicide during the deposition of the metal [14].…”

Effect of chemical order on the magnetic and electronic properties of epitaxial off-stoichiometryFexSi1−xthin films

“…found a reduction in the magnetic moment with increasing Si concentration and attributed it to increased Si NN around Fe II atoms and a reduction in the total number of Fe I atoms with decreasing x. 6 However, the local chemical order was not clarified and the electronic structure was not investigated in that work.…”
