Field-induced effects in the spin liquid candidate PbCuTeO
Paul Eibisch, Christian Thurn, Arif Ata +9
PbCuTeO is considered as one of the rare candidate materials for a three-dimensional quantum spin liquid (QSL). This assessment was based on the results of various magnetic…
Non-Abelian statistics in light scattering processes across interacting Haldane chains
Vladimir Gnezdilov, Vladimir Kurnosov, Yurii Pashkevich +6
The Haldane state is constructed from a product of local singlet dimers in the bulk and topological states at the edges of a chain. It is a fundamental representative of topo…
Spin liquid and ferroelectricity close to a quantum critical point in PbCuTeO
Christian Thurn, Paul Eibisch, Arif Ata +13
Geometrical frustration among interacting spins combined with strong quantum fluctuations destabilize long-range magnetic order in favour of more exotic states such as spin liquids…
Experimental Observation of Bethe Strings
Zhe Wang, Jianda Wu, Wang Yang +8
Almost one century ago, string states - complex bound states (Wellenkomplexe) of magnetic excitations - have been predicted to exist in one-dimensional quantum magnets and since th…
The magnetic Hamiltonian and phase diagram of the quantum spin liquid Ca10Cr7O28
Christian Balz, Bella Lake, A. T. M. Nazmul Islam +6
A spin liquid is a new state of matter with topological order where the spin moments continue to fluctuate coherently down to the lowest temperatures rather than develop static lon…
Crystal growth, structure and magnetic properties of Ca10Cr7O28
Christian Balz, Bella Lake, Manfred Reehuis +5
A detailed diffraction study of Ca10Cr7O28 is presented which adds significant new insights into the structural and magnetic properties of this compound. A new crystal structure ty…
Physical realization of a quantum spin liquid based on a novel frustration mechanism
Christian Balz, Bella Lake, Johannes Reuther +11
Unlike conventional magnets where the magnetic moments are partially or completely static in the ground state, in a quantum spin liquid they remain in collective motion down to the…
From confined spinons to emergent fermions: Observation of elementary magnetic excitations in a transverse-field Ising chain
Zhe Wang, Jianda Wu, Shenglong Xu +11
We report on spectroscopy study of elementary magnetic excitations in an Ising-like antiferromagnetic chain compound SrCoVO as a function of temperature and applied tra…
Multiple lattice instabilities resolved by magnetic-field and disorder sensitivities in cubic paramagnetic phase of the orbital-degenerate frustrated spinel MgVO
Tadataka Watanabe, Takashi Ishikawa, Shigeo Hara +3
Ultrasound velocity measurements of the orbital-degenerate frustrated spinel MgVO are performed in the high-purity single crystal which exhibits successive structural and a…
Softened magnetic excitations in the s = 3/2 distorted triangular antiferromagnet alpha-CaCr2O4
Dirk Wulferding, Kwang-Yong Choi, Peter Lemmens +5
The spin dynamics and magnetic excitations of the slightly distorted triangular s = 3/2 system alpha-CaCr2O4 are investigated by means of Raman spectroscopy and electron spin reson…
Fabrication of submicron LaSrCuO intrinsic Josephson junction stacks
Yuimaru Kubo, Yamaguchi Takahide, Takayoshi Tanaka +6
Intrinsic Josephson junction (IJJ) stacks of cuprate superconductors have potential to be implemented as intrinsic phase qubits working at relatively high temperatures. We report s…
Coupled spin-lattice fluctuations in a compound with orbital degrees of freedom: the Cr based dimer system Sr3Cr2O8
Dirk Wulferding, Peter Lemmens, Kwang-Yong Choi +5
We report on an extended fluctuation regime in the spin dimer system Sr3Cr2O8 based on anomalies in Raman active phonons and magnetic scattering. The compound has two characteristi…
Spin and Orbital Order of the Vanadium Spinel MgV2O4
Elisa M. Wheeler, Bella Lake, A. T. M. Nazmul Islam +4
We present a unique study of the frustrated spinel MgV2O4 which possesses highly coupled spin, lattice and orbital degrees of freedom. Using large single-crystal and powder samples…
