Exchange Anisotropy of L1$_2$-Mn$_3$X (X$=$Ir, Rh, Ru)/Co-Fe Bilayers

Interfacial spin effects on Hex in metallic polycrystalline exchange biased systems

“…1 Antiferromagnetic ͑AF͒ layers with high magnetocrystalline anisotropy K are required for stability. 4 This improvement has been obtained by means of substrate heating or thermal annealing. 2 Recently, Imakita et al 3 and Tsunoda et al 4 have shown that L1 2 -ordered IrMn 3 / CoFe is a good candidate for the production of magnetic tunnel junctions due to the high anisotropy of IrMn and annealing tolerance.…”

Compositional Dependence of Exchange Anisotropy in .GAMMA.-Mn-Ir-Rh-Ru / Co70Fe30 Bilayers

“…Mn-Rh and Mn-Ru alloys of either disorder 5) or order 6) phase around 75 at.% of Mn show comparable exchange bias properties to Mn-Ir alloy in the bilayer system. While the exchange bias properties of Mn-Rh and Mn-Ru do not exceed those of Mn-Ir in the binary system, multi-element alloy system still have a potential to overcome Mn-Ir.…”

Observation of an anomalous Hall effect in single-crystal Mn3Pt

“…The cubic compounds, on the other hand, have a triangular spin configuration in which the spins do point in equivalent directions. Therefore, the magnetic anisotropy is 2-3 orders of magnitude higher than for the hexagonal compounds [17][18][19][20], a property that has made one member of this family, Mn 3 Ir, technologically important as an exchange-bias layer [21][22][23][24]. The room-temperature magnetic structure of Mn 3 Pt is shown in figure 1.…”
