Two Coupled Chains are Simpler than One: Field-induced Chirality in a Frustrated Quantum Spin Ladder
M. Pikulski, T. Shiroka, F. Casola +5
Although the frustrated spin chain (zigzag chain) is a Drosophila of frustrated magnetism, the understanding of a pair of coupled zigzag chains (frustrated spin ladder) in a magnet…
From order to randomness: Onset and evolution of the random-singlet state in bond-disordered BaCu(SiGe)O spin-chain compounds
T. Shiroka, F. Eggenschwiler, H. -R. Ott +1
Heisenberg-type spin-chain materials have been extensively studied over the years, yet not much is known about their behavior in the presence of disorder. Starting from BaCuSi$…
Pressure and magnetic field effects on a quasi-2D spin-1/2 Heisenberg antiferromagnet
N. Barbero, T. Shiroka, C. P. Landee +3
Cu(pz)2(ClO4)2 (with pz denoting pyrazine, C4H4N2) is among the best realizations of a two-dimensional spin-1/2 square-lattice antiferromagnet. Below T_N = 4.21 K, its weak interla…
Impact of strong disorder on the static magnetic properties of the spin-chain compound BaCu2SiGeO7
T. Shiroka, F. Casola, W. Lorenz +3
The disordered quasi-1D magnet BaCu2SiGeO7 is considered as one of the best physical realizations of the random Heisenberg chain model, which features an irregular distribution of…
Field-induced quantum soliton lattice in a frustrated two-leg spin-1/2 ladder
F. Casola, T. Shiroka, A. Feiguin +10
The field-induced quantum phase transitions (QPT) of the spin ladder material Bi(Cu(1-x)Znx)2PO6 have been investigated via 31P nuclear magnetic resonance (NMR) on single-crystal s…
Dimensional crossover of spin chains in a transverse staggered field: an NMR study
F. Casola, T. Shiroka, V. Glazkov +6
Heisenberg spin-1/2 chain materials are known to substantially alter their static and dynamic properties when experiencing an effective transverse staggered field originating from…
