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…
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…
Strong exchange anisotropy in YbMgGaO from polarized neutron diffraction
Sándor Tóth, Katharina Rolfs, Andrew R. Wildes +1
We measured the magnetic correlations in the triangular lattice spin-liquid candidate material YbMgGaO via polarized neutron diffraction. The extracted in-plane and out-of-plan…
