Combined reactions associated with L10 ordering

Journal of Magnetism and Magnetic Materials, 2003
Abstract Recently, self-organized magnetic arrays (SOMAs) have received a great deal of attention because of the potential of achieving magnetic data storage densities greater than 1 Tbit/in 2 . SOMA involves the chemical preparation of self-assembled arrays of alloyed nanoparticles (such as FePt), which can be subsequently annealed to form an L1 0 ...

Crystallographic aspects of L10 magnetic materials

Scripta Materialia, 2005
In this paper we present an overview of various features of the structure of L10 magnetic phase. We discuss the various microstructural features which occur in these materials due to the changes in symmetry (translational and orientational domains) as well as the relationship between the crystal symmetry and features such as the thermodynamic order of ...

Enhancing the Ordering and Coercivity of L10 FePt Nanostructures with Bismuth Additives for Applications Ranging from Permanent Magnets to Catalysts

ACS Applied Nano Materials, 2019
L10 highly ordered FePt nanostructures were successfully synthesized following a direct one-step liquid phase chemical approach. The enhanced ordering was achieved with the use of bismuth additives in the reaction mixture.

Magnetism of L10 Stacked Multilayers

physica status solidi (b), 2000
We present a systematic study of magnetic and electronic properties of monoatomic multilayers consisting of 3d transition metals and noble metals Au and Cu stacked in the L1 0 structure by the first principles tight-binding linearized muffin tin orbital (TB-LMTO) method.

L10 versus Leq—A User's Perspective

1979
The Federal Highway Administration (FHWA) regulation tor highway traffic noise analysis, FHPM 7-7-3, allows for the use of either L10 (sound level exceeded 10 percent of the time) or Leq (energy equivalent sound level). Therefore, state highway agencies have the responsibility to empirically determine the preferable descriptor (L10 or Leq) for typical ...

Order Parameter in L10 FePt Nanocrystals

Transactions of the Indian Institute of Metals, 2014
FePt nanocrystals with L10 chemical order have high magnetic anisotropy. FePt nanocrystals with fcc structure need to be heated to 600 °C to form the hard magnetic L10 phase. The order parameter (S) in nanocrystals changes during annealing. The order parameter in L10 FePt nanocrystals determines the relation between chemical ordering in this structure ...

Dot size dependence of magnetic properties in microfabricated L10-FePt (001) and L10-FePt (110) dot arrays

Journal of Applied Physics, 2006
L 1 0 - Fe Pt (001) and L10-FePt (110) dot arrays with well-defined geometry were fabricated through the use of electron beam lithography and Ar ion etching. The lateral size of dots was varied in the range from 0.2×0.2to5×5μm2. Coercivity (Hc) for the perpendicularly magnetized FePt (001) dots increases with decreasing the dot size. In the case of the
