Magnetism of FePt surface alloys.
The complex correlation of structure and magnetism in highly coercive monoatomic FePt surface alloys is studied using scanning tunneling microscopy, x-ray magnetic circular dichroism, and ab initio theory. Depending on the specific lateral atomic coordination of Fe either hard magnetic properties comparable to that of bulk FePt or complex noncollinear magnetism due to Dzyaloshinski-Moriya inter...
متن کاملMagnetism, elasticity, and magnetostriction of FeCoGa alloys
It is known that the substitution of Co for Fe gives rise to increases in magnetization and Curie temperature, not only in the bcc metals, but also in intermetallic compounds and alloys as well. With the expectation that this is the case in Co-substituted FeGa, we measured magnetization, Curie temperature, magnetostriction and elastic constants of a series of polycrystalline FeCoGa ternary allo...
متن کاملElectronic structure and magnetism of Fe1ÀxPdx alloys
An ab initio linearized augmented plane-wave method has been employed to calculate the electronic and magnetic structures of both face-centered-cubic and body-centered-cubic Fe12xPdx alloys with x50.25, 0.50, and 0.75, respectively. Decreasing the Pd content in Fe12xPdx alloy from x51, the magnetic ordering of fcc Fe12xPdx changes from paramagnetism to ferromagnetism, ferrimagnetism, and finall...
متن کاملMagnetism of Less Common Cobalt-Rich Alloys
Alternative permanent-magnet materials with intermediate performance, such as K1 , are investigated experimentally. Our focus is on the structural and magnetic properties of bulk YCo5-xFex and on rare-earth-free transition-metal alloys such as TMxCo100-x (TM = Zr, Hf). YCo5-xFex alloys (x = 0 to 0.75), which crystallize in the hexagonal CaCu5-type structure, exhibit an improved of anisotropy an...
متن کاملMagnetism and magnetic asphericity in NiFe alloys
We here study magnetic properties of NixFe1−x using Augmented space recursion technique coupled with tight-binding linearized muffin tin orbital method. Also the spectral properties of this alloy has been studied here. PACS numbers: 71.20.-b,71.23.-k,71.20.Be,71.15.-m
