Preparation of L10 ordered CuAu buffer layer and its effect on the L10 ordering in the FePt thin film

Thin Solid Films, 2003
Abstract The L10 ordering in co-sputtered CuAu films was investigated at first. It is found that the Cu50Au50 (at.%) film starts L10 ordering above the 100 °C substrate temperature, and can be fully L10 ordered (long-range order parameter S≈1) at the 450 °C substrate temperature.

The impact of dislocations on coercivity in L10-MnAl

Journal of Alloys and Compounds, 2017
Abstract Two different transformation routes, quenching followed by heat treatment (route 1), and cooling at intermediate rate (route 2), were used to obtain the L1 0 phase in Mn-Al alloys. The resulting materials showed remarkable differences in microstructure and magnetic properties. In addition, fully transformed material was cold-worked and then

Structural studies of L10 FePt nanoparticles

Applied Physics Letters, 2002
We have studied the lattice parameter changes of L10 FePt nanoparticles annealed to near equilibrium as a function of composition by x-ray diffraction. We have found that the (111) diffraction peak shifts linearly with composition, however, the c parameter mostly changes in the Pt rich compositions and the a parameter mostly changes in the Fe rich ...

Attenuation of L10 by long barriers

Journal of Sound and Vibration, 1975
The theoretical attenuation of traffic noise by long barriers has been studied, by using a Monte Carlo snapshot technique for description of individual vehicle contributions, and the results compared with those obtained when line and point source approximations are used for the traffic noise source.

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 ...

Influence of honking on the noisier situation (L10)

Noise Control Engineering Journal, 2012
A study of noise due to honking and its impact on L10 has been carried out at Kolkata metropolis. The relation between L10, honking, traffic and the percentage of heavy vehicle has been determined. L10, the noise level that exceeds 10% of the monitoring time, is a measure of the higher noise level.

Nanoporous L10-FePt with high coercivity

Scripta Materialia, 2019
Abstract We demonstrate the synthesis of a novel nanoporous ordered face-centered tetragonal FePt (L10-FePt) compound by selective dissolution of an Fe60Pt10B30 nanocomposite alloy, which consists of nanoscale L10-FePt and Fe2B phases. The Fe2B phase is selectively removed from the alloy by electrochemical etching in H2SO4 aqueous solution, while the

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.

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 ...
