Fe68Pd32 nanoparticles were prepared by sonoelectrodeposition with subsequent annealing at 600 oC for a series of times from 1 h to 6 h. The transformed disordered face-centered cubic (fcc) phase in the as-prepared samples into multi-phase material containing an ordered L10 FePd, fcc FePd and body-centered (bcc) Fe phases. After 600°C hard magnetic L10-FePd soft fcc-FePd coexist. structural pro...

Ni based magnetic shape memory alloys (MSMAs) have broad applications in actuators and MEMS devices. Two-stage stress induced martensitic phase transformation, a widely observed phenomenon in these alloys, is described conventionally as a fi rst stage L21 (austenite)-to-10M/14M (M: modulated martensite) transition, followed by a second stage 14M-to-L10 (tetragonal martensite) transformation at ...

A combination of finite energy sum rule techniques and Chiral Perturbation Theory (χPT) is used in order to exploit recent ALEPH data on the non-strange τ vector (V ) and axial-vector (A) spectral functions with respect to an experimental determination of the χPT quantity L10. A constrained fit of R (k,l) τ,V−A inverse moments (l < 0) and positive spectral moments (l ≥ 0) adjusts simultaneously...

Lately, there has been great interest in performing free-energy perturbation (FEP) at the combined quantum mechanics and molecular mechanics (QM/MM) level, e.g. for enzyme reactions. Such calculations require extensive sampling of phase space, which typically is prohibitive with density-functional theory or ab initio methods. Therefore, such calculations have mostly been performed with semiempi...

Thickness modulation at the edges of nanostructured magnetic thin films is shown to have important effects on their perpendicular magnetic anisotropy. Thin film wires with tapered edges were made from [Co/Pd]20 multilayers or L10-FePt films using liftoff with a double-layer resist. The effect of edge taper on the reversal process was studied using magnetic force microscopy (MFM) and micromagnet...

In this paper, we illustrate how to modify the structure and magnetic properties of L10 FePt and PtMn films using ion-beam irradiation. Highly ordered L10 FePt and PtMn phases were achieved directly by using 2 MeV He-ion irradiation without conventional post-annealing. A high ion-beam current density (~μA/cm ) was used to achieve direct beam heating on samples. This irradiation-induced heating ...

The effects of growth rate (Gr), deposition temperature (Td), film thickness (tF ), and substrate induced strain (ǫ) on morphological, crystallographic and magnetic characteristics of equiatomic CoPt epitaxial films synthesized with pulsed laser deposition (PLD) are investigated. The (001) oriented single crystal substrates of MgO, SrTiO3 and LaAlO3 provide different degree of epitaxial strain ...

We report on the out-of-plane thermal conductivities of tetragonal L10 FePt (001) easy-axis and cubic A1 FePt thin films via time-domain thermoreflectance over a temperature range from 133 K to 500 K. The out-of-plane thermal conductivity of the chemically ordered L10 phase with alternating Fe and Pt layers is ~23% greater than the thermal conductivity of the disordered A1 phase at room tempera...

The milk fat globule (MFG) is one of the most representative of mammary gland tissues and can be utilized to study gene expression of lactating cows during lactation. In this study, RNA-seq technology was employed to detect differential expression of genes in MFGs at day 10 and day 70 after calving between two groups of cows with extremely high (H group) and low (L group) 305-day milk yield, mi...

Yeast ribosomal protein L10 (E. coli L16) is located at the center of a topological nexus that connects many functional regions of the large subunit. This essential protein has previously been implicated in processes as diverse as ribosome biogenesis, translational fidelity and mRNA stability. Here, the inability to maintain the yeast Killer virus was used as a proxy for large subunit defects t...
