  1. 2637. Geometric Magnetic Frustration in Correlated Metallic Systems
    S R Dunsiger (TRIUMF)
    03/06/2019, 10:45
    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Oral (Non-Student) / Orale (non-étudiant(e))

    Systems based on lattices of triangular or tetrahedral units with nearest neighbour antiferromagnetic exchange interactions are the archetypal examples of geometric magnetic frustration, offering a means of accessing novel ground states. Rich phenomenology has similarly been observed in extensive investigations of Ce (4f1) and Yb (4f13) based intermetallic compounds, including heavy fermion...

  2. 2526. Frustrated magnetism on 2D triangular, metallic antiferromagnets
    Eundeok Mun

    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Oral (Non-Student) / Orale (non-étudiant(e))

    For Ce- and Yb-based metallic systems, the competition between Kondo and RKKY interactions results in a great variety of ground states. When these rare-earth ions are located on the geometrically frustrated lattices, the magnetic order may be tuned by the introduction of magnetic frustration. Although the lattices are geometrically frustrated for the short range, nearest neighbor spin-spin...

  3. 2530. Physical properties of Yb3Ru4Ge13 and Lu3Ru4Ge13
    Jeonghun Lee (Simon Fraser University)
    03/06/2019, 11:15
    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Cubic compounds with Yb3Rh4Sn13-type structure have drawn attention because of their rich ground states such as heavy fermion behavior, intermediate valence behavior, charge density wave, and superconductivity. In this talk, we will present the structural, magnetic, and electrical properties of cubic R3Ru4Ge13 (R = Yb and Lu) compounds. Single crystals of R3Ru4Ge13 were characterized by...

  4. 2761. From Quantum Spin Ice to Ordered Spin Ice in the Pyrochlore Tb2Ge2O7
    Alannah Hallas (Department of Physics and Astronomy and SBQMI, University of British Columbia)

    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Invited Speaker / Conférencier(ère) invité(e)

    The rare earth pyrochlores family of materials that are renowned for the diversity and novelty of their magnetic ground states. However, despite more than 20 years of effort, a consensus on the nature of the magnetic ground states of the terbium pyrochlores has remained elusive. Indeed, there are numerous confounding factors that come into play in these materials, including: a low-lying...
