Field-induced quasi-bound state within the two-magnon continuum of a square-lattice Heisenberg antiferromagnet
F. Elson, M. Nayak, A. A. Eberharter +14
Quantum magnets in two dimensions display strong quantum interaction effects even when magnetically ordered. Using the metal-organic framework material CuF(DO)(pyz), we…
Phonon spectrum in the spin-Peierls phase of CuGeO
L. Spitz, A. Razpopov, S. Biswas +10
CuGeO has long been studied as a prototypical example of the spin-Peierls transition in a Heisenberg chain. Despite intensive investigation of this quasi-one-dimensio…
Magnetic order and exchange couplings in the frustrated diamond lattice antiferromagnet MnScSe
K. Guratinder, V. Tsurkan, L. Prodan +6
We report the magnetic properties of -site spinel compound MnScSe. The macroscopic magnetic measurements uncovers successive magnetic transitions at = 2.04…
Revealing three-dimensional quantum criticality by Sr-substitution in Han Purple
Stephan Allenspach, Pascal Puphal, Joosep Link +20
Classical and quantum phase transitions (QPTs), with their accompanying concepts of criticality and universality, are a cornerstone of statistical thermodynamics. An exemplary cont…
Floating Zone Growth of Sr Substituted Han Purple: BaSrCuSiO
Pascal Puphal, Stephan Allenspach, Christian Rüegg +1
We present a route to grow single crystals of BaSrCuSiO suitable for inelastic neutron studies via the floating zone technique. Neutron single crystal d…
Impurities in weakly coupled quantum spin chains SrCuO and SrCuO
Koushik Karmakar, Rabindranath Bag, Markos Skoulatos +2
We study the effect of non-magnetic Zn (spin-) and magnetic Ni (spin-) impurities on the ground state and low-lying excitations of the quasi-one-dimensional spi…
