Two new isostructural layered oxohalides FeTe3O7X (X = Cl, Br) were synthesized by chemical vapor transport reactions, and their crystal structures and magnetic properties were characterized by single-crystal X-ray diffraction, Raman spectroscopy, magnetic ...
Using density matrix renormalization group (DMRG) and perturbative continuous unitary transformations (PCUTs), we study the magnetization process in a magnetic field for all coupling strengths of a quasi-1D version of the 2D Shastry-Sutherland lattice, a f ...
NMR measurements of the Si-29 spin-lattice relaxation time T-1 were used to probe the spin-1/2 random Heisenberg chain compound BaCu2(Si1-xGex)(2)O-7. Remarkable differences between the pure (x = 0) and the fully random (x = 0.5) cases are observed, indica ...
This paper introduces the concept of ring magnets for magnetic beads (MBs) trapping in a capillary. Such magnets enable an easy insertion of a capillary simply like a pearl on a string. With this system, high magnetic forces are obtained thanks to the prox ...
In this study, we measured the temperature-dependent magnetic susceptibility [chi(T)], ac magnetic susceptibility [chi(ac)(T)], specific heat [C-p(T)], and high-field magnetization [M(H)] of a newly synthesized single-crystalline material, Co3TeO6. Two tra ...
Direction reversals of intrinsic toroidal rotation have been observed in Alcator C-Mod ohmic L-mode plasmas following modest electron density or toroidal magnetic field ramps. The reversal process occurs in the plasma interior, inside of the q = 3/2 surfac ...
The temperature and magnetic field dependent magnetization of the two-dimensional quantum spin system Ni-5(TeO3)(4)Cl-2 has been investigated using single crystals in temperature range 1.8-100 K and in magnetic fields up to 14 T. The magnetization below th ...
Direction reversals of intrinsic toroidal rotation have been observed in diverted Alcator C-Mod Ohmic L-mode plasmas following electron density ramps. For low density discharges, the core rotation is directed cocurrent, and reverses to countercurrent follo ...
We report on magnetization and specific heat measurements on single-crystalline CuTe2O5. The experimental data are directly compared to theoretical results for two different spin structures, namely an alternating spin-chain and a two-dimensional (2D) coupl ...
We present magnetization and Se-77 Nuclear Magnetic Resonance (NMR) measurements in single crystals of the magnetoelectric compound Cu2OSeO3. The temperature and field dependence of the magnetization suggest a ferrimagnetic ordering at T-c similar or equal ...
