Exchange bias in ferromagnet/antiferromagnet bilayers

“…[19] At the same time, atomic magnetic moments of Fe and Mn were determined to be 1.0±0.2 µ B and 1.2 ± 0.2 µ B , respectively. [20] The CrAl alloy with 18 at.% Al is an AFM with Neél temperature of 500 • C-600 • C [21] and the spin structure of a spin density wave is formed with the atomic magnetic moment of about 1.0 µ B . [22] Dependence of the EB on the thickness of constituent layers has been studied extensively.…”

Effect of adding cobalt on mechanical and structural properties of Cu–2Be alloy aged below half its melting temperature

“…3 Indeed, in this alloy, remarkable precipitation strengthening occurs with hardness values comparable with those of steels. 4 However, the structures produced by the decomposition of a supersaturated solid solution of beryllium in copper at low aging temperatures have often proved difficult to resolve and interpreted partly due to the high density of precipitation.…”

Atomistic potential for TaSi system: application to low-index interfaces

“…Moreover, the heat of formation of several tantalum silicides is negative and thus a silicide layer should be observed in between Ta and Si. TaSi 2 with the C40 crystal structure is the most common silicide observed in silicon metallization [5], but some studies also report the formation of Ta 5 Si 3 [6], which has the tetragonal D8 m structure [7]. Tantalum barrier stability can be improved slightly by adding nitrogen to the barrier layer [8].…”
