    Abstract : In the present information age, people across the globe generate an enormous digital footprint. Therefore, it is necessary to store and process the information in an elegant way. Spin-logic circuits are being considered potential candidates beyond CMOS integrated computing due to high clock speed, non-volatility, and higher logical efficiency. READ MORE

  4. 2. The interaction of light and magnetism in the TbxCo100-x system

    Author : Agne Ciuciulkaite; Vassilios Kapaklis; Pablo Maldonado; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetism; rate-earth transition metal alloys; light-magnetism interaction; all-optical switching; Fysik; Physics;

    Abstract : Development of the faster and denser magnetic memory storage elements has been an active area of research since early 20th century. The path of research on magnetization manipulation began with firstly changing the magnetization state of a medium in an external magnetic field, then heating of a medium and magnetizing with a permanent magnet was explored, while the latest efforts have been focused on switching the magnetization only by a polarized laser light.
