Abstract
Effect of magnetic field on microstructure formation through a disorder-order transformation has been studied in FePd alloy. Single crystal of the disordered Fe-55at%Pd is subjected to an ordering heat-treatment under a magnetic field. When the ordering heat-treatment is performed without applying a magnetic field, three lattice corresponding variants are formed equivalently. On the other hand, when the ordering heat-treatment is made under a magnetic field of 4 T and higher applied along the [001] direction of the disordered phase, a single variant with an easy axis along the field direction is obtained. A tweed microstructure has been observed at early stage of ordering with streaks in the <011> directions. High density of antiphase boundary after formation of a single variant indicates the formation of homogeneous nucleation of the ordered L10 phase in a disordered fcc matrix at the early stage of ordering.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
