  1. 17. Neutron scattering in magnetic fields up to 26 T using HFM/EXED facility

    Experience with static fields | Science & Techniques
    Oral

    Application of high magnetic fields is a powerful method for revealing a complex behaviour in modern materials. In combination with a microscopic probe such as neutrons it provides a direct access to static and dynamic correlations in matter. Until the shutdown of the BERII research reactor in 2019, Helmholtz-Zentrum Berlin (HZB) hosted a unique high field facility for neutron scattering. It...

    The quasi-two-dimensional quantum magnetic compound BaCuSi2O6, an ancient pigment also known as Han Purple, consists of three different types of stacked, square-lattice bilayers hosting spin-1/2 dimers. This material undergoes a magnetic-field-induced quantum phase transition at a critical field of 23.35 T from a quantum disordered to a magnetically ordered state that resembles the XY...

    Magnetic field is a fundamental thermodynamical parameter having a potential to change the miscroscopic arrangement of magnetic moments or even to create them in the first place. To disclose the spatial arrangement, nature and magnitude of magnetic moments involved in a long-range magnetic order, neutron diffraction is still the method of choice. However, the relatively weak interaction...

  4. 4. Next generation asymmetric horizontal SANS magnet for quantum phenomena in nanostructures and correlated electron systems
    Dr Sebastian Mühlbauer (FRM II — Forschungs-Neutronenquelle Heinz Maier-Leibnitz)

    Inspiration for the use of high-B fields
    Oral

    The main goal of the project “Next generation asymmetric horizontal SANS magnet for quantum phenomena in nanostructures and correlated electron systems” is the development of a high performance compensated asymmetric horizontal magnet optimized for small angle neutron scattering (SANS), reflectometry and the resonance spin echo technique MIEZE [1] (Modulation of IntEnsity with Zero Effort)....

    Experience with static fields | Science & Techniques
    Oral

    Purely organic magnets with -electron spins have essentially negligibly small spin-orbit couplings and are attractive materials because they are archetypical Heisenberg spin systems in which the quantum fluctuations play an important role. The spin size and the connectivity of the network is the key factor of the novel magnetic states arising from quantum fluctuation. Among the representative...

  6. 18. HTS insert based on the metal-as-insulation winding technology as a step forward to very high field superconducting magnet

    Experience with static fields | Science & Techniques
    Oral

    Recently, several technological breakthroughs have confirmed the practical feasibility of superconducting solenoid magnets generating more than 30 T, based on a large traditional low-temperature superconducting (SBT) magnet, in which an insert based on high temperature superconductors (HTS) is introduced. In addition to a very significant reduction in electrical energy consumption, they also...
