    Author : Ronny Knut; Olof Karis; Biplab Sanyal; Hermann Durr; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Spintronics; X-ray photoemission; XPS; XMCD; XAS; magnetic semiconductors; HIKE; HAXPES; multilayer; monte carlo; magnetism; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Materials exhibiting new functionalities due to interdependent electric (e.g. conductivity) and magnetic properties are potentially interesting for spintronics applications. READ MORE

  4. 2. First Principle Studies of Functional Materials : Spintronics, Hydrogen Storage and Cutting Tools

    Author : Fredrik Silvearv; Ahuja Rajeev; Ali Zaoui; Uppsala universitet; []
    Keywords : spintronics; hydrogen storage; coating materials; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The properties of functional materials have been studied with density functional theory. The first type of materials that have been investigated is the so called diluted magnetic semiconductors. It is a new class of materials that could offer enhanced functionality by making use of spin in addition to the charge of the electron. READ MORE

  5. 3. Density Functional Theory Applied to Materials for Spintronics

    Author : Diana Mihaela Iusan; Olle Eriksson; Biplab Sanyal; Hiroshi Katayama-Yoshida; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; spintronics; dilute magnetic semiconductors; density functional theory; exchange interactions; magnetic percolation; ordering temperature; disorder; electronic structure; Physics; Fysik; Materialvetenskap; Materials Science;

    Abstract : The properties of dilute magnetic semiconductors have been studied by combined ab initio, Monte Carlo, and experimental techniques. This class of materials could be very important for future spintronic devices, that offer enriched functionality by making use of both the spin and the charge of the electrons. READ MORE

  6. 4. Electronic Structure and Statistical Methods Applied to Nanomagnetism, Diluted Magnetic Semiconductors and Spintronics

    Author : Lars Bergqvist; Olle Eriksson; Warren Pickett; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; spintronics; magnetism; Monte Carlo; critical temperature; exchange interactions; percolation; disorder; noncollinear; electronic structure; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : This thesis is divided in three parts. In the first part, a study of materials aimed for spintronics applications is presented. More specifically, calculations of the critical temperature in diluted magnetic semiconductors (DMS) and half-metallic ferromagnets are presented using a combination of electronic structure and statistical methods.

  7. 5. Preparation and characterization of an organic-based magnet

    Author : Elin Carlegrim; Mats Fahlman; Svante Svensson; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic-based magnets; spintronics; photoelectron spectroscopy; near edge x-ray absorption fine structure spectroscopy; chemical vapor deposition; physical vapor deposition; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : In the growing field of spintronics there is a strong need for development of flexible lightweight semi-conducting magnets. Molecular organic-based magnets are attractive candidates since it is possible to tune their properties by organic chemistry, making them so-called “designer magnets”. READ MORE
