Brillson and Yicheng Lu J. Appl. Phys. 109, 121301 Research Highlights Numerical analysis of plasma evolution on dielectric barrier discharge plasma actuator Hiroyuki Nishida and Takashi Abe Time evolution of the discharge plasma in the dielectric barrier discharge plasma actuator was simulated by the simple fluid model in which the electron and single positive ion species were considered. It was shown that even the simple numerical model could provide valuable insights into the physics of DBD plasma actuator; this indicates that the positive ions and electrons play a prominent role in determining the general characteristics of the plasma evolution. J. Appl. Phys. 110, 013302 (2011) Micromagnetic study on microwave-assisted magnetic recording in perpendicular medium with intergrain exchange coupling Yukio Nozaki, Ayumu Kato, Kenji Noda, Yasushi Kanai, Terumitsu Tanaka, and Kimihide Matsuyama The results of micromagnetic simulation suggest that the microwave frequency realizing the magnetization reversal is increased as the exchange stiffness constant among the magnetic grains becomes larger than 1 × 10⁻⁷ erg/cm if an inhomogeneous magnetization reversal occurred. The numerically expected increase in the microwave frequency was observed experimentally in perpendicularly magnetized Co/Pd multilayer with an exchange stiffness constant of ∼1 × 10⁻⁶ erg/cm. J. Appl. Phys. 109, 123912 (2011) Largely enhanced energy density in epitaxial SmCo₅/Fe/SmCo₅ exchange spring trilayers S. Sawatzki, R. Heller, Ch. Mickel, M. Seifert, L. Schultz, and V. Neu In order to enhance the energy density (BH)max as a key property for permanent magnet applications, exchanged-coupled trilayers of SmCo₅/Fe/SmCo₅ with fixed SmCo₅ layer thicknesses (25 nm) and varying soft magnetic Fe film thickness have been epitaxially grown by pulsed laser deposition on Cr buffered MgO(110) substrates. J. Appl. Phys. 109, 123922 (2011) More Research Highlights Journal of Applied Physics retains spot as second most highly cited journal in Applied Physics Journal metrics just released by Thomson Reuters, once again show Journal of Applied Physics (JAP) to be the second most highly cited journal tracked in the Applied Physics category, with 119,644 citations in 2010. JAP is eclipsed only by another AIP publication, Applied Physics Letters.
