Field-tunable Berezinskii-Kosterlitz-Thouless correlations in a Heisenberg magnet

D. Opherden, M. S. J. Tepaske, F. Bärtl +10

We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT) correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk materia…

Freezing of molecular rotation in a paramagnetic crystal studied by $^{31}$ P NMR

D. Opherden, F. Bärtl, Sh. Yamamoto +9

We present a detailed $^{31}$ P nuclear magnetic resonance (NMR) study of the molecular rotation in the compound [Cu(pz) $_{2}$ (2-HOpy) $_{2}$ ](PF $_{6}$ ) $_{2}$ , where pz = C $_{4}$ H $_{4}$ N…

Quantum-critical spin dynamics in a Tomonaga-Luttinger liquid studied with muon-spin relaxation

J. S. Möller, T. Lancaster, S. J. Blundell +7

We demonstrate that quantum-critical spin dynamics can be probed in high magnetic fields using muon-spin relaxation ( $μ^{+}$ SR). Our model system is the strong-leg spin ladder bis(…

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…

Raman study of spin excitations in the tunable quantum spin ladder Cu(Qnx)(Cl $_{1 - x}$ Br $_{x}$ ) $_{2}$

G. Simutis, S. Gvasaliya, F. Xiao +2

Raman spectroscopy is used to study magnetic excitations in the quasi one dimensional $S = 1/2$ quantum spin systems Cu(Qnx)(Cl $_{1 - x}$ Br $_{x}$ ) $_{2}$ . The low energy spectrum is found t…

ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase

M. Ozerov, M. Maksymenko, J. Wosnitza +6

Magnetic excitations in the strong-leg quantum spin ladder compound (C $_{7}$ H $_{10}$ N) $_{2}$ CuBr $_{4}$ (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are stud…
