    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spin-spin; Spin-Orbit; D and E parameters; ZFS; graphene; TMM; OXA; diradicals; tris 8-hydroxyquinonline aluminium; magnetic anisotropy; magnetism; triplet;

    Abstract : The underlying theory of “Spin” of an electron and its associated inter-actions causing internal fields and spectral shift to bulk-magnetism iswell established now. Our understanding of spin properties is significant andmore useful than ever before. READ MORE

    Abstract : This thesis is a theoretical investigation of the effects of spin-orbit (SO) interactions in ferromagnetic metal nano-particles. Part I of the thesis is devoted to an elementary introduction of the research field, including recent experimental advances which partly motivated the work presented here. READ MORE

  5. 3. Spin-Spin and Spin-Orbit coupling studies of small species and magnetic system

    Author : Sathya S R R Perumal; Olav Vahtras; Ulf Wahlgren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin-spin; spin-orbit; biradical; mcscf; Theoretical chemistry; Teoretisk kemi;

    Abstract : The spin of an electron often misleadingly interpreted as the classical rotationof a particle. The quantum spin distinguishes itself from classicalrotation by possessing quantized states and can be detected by its magneticmoment. The properties of spin and its collective behavior with otherfundamental properties are fascinating in basic sciences. READ MORE

  6. 4. Spin-orbit coupling in transition metal systems : a study of octahedral Ni(II)

    Author : Carl Ribbing; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The effects induced by spin-orbit coupling on the electronic states of Ni(II) complexes are studied with ab-initio and crystal field calculations.The ab-initio calculations are performed in two steps, to separate the coulomb and the spin-orbit effects. READ MORE

  7. 5. Effects of the Spin-Orbit Interaction on Transport and Optical Properties of III-V Semiconductor Quantum Wells

    Author : Vladimir Froltsov; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin-orbit interaction; quantum well; III-V; Raman scattering; magnetoresistance; weak localization; spin distribution; magnetic field; Fysik; Physics; Fysicumarkivet A:2000:Froltsov; Halvledarfysik; Semiconductory physics; semiconductor;

    Abstract : Effects of the intrinsic electron spin-orbit interaction on transport and optical properties of III-V semiconductor quantum wells have been studied theoretically. It is shown that due to crystal anisotropy of this interaction, the weak localization magnetoresistance in a magnetic field parallel to interfaces is very sensitive to the epitaxy growth direction and also to the orientation of the magnetic field with respect to the crystal axes.
