Observation of a multiferroic critical end point
Jae Wook Kim, S. Y. Haam, Y. S. Oh +9
The study of abrupt increases in magnetization with magnetic field known as metamagnetic transitions has opened a rich vein of new physics in itinerant electron systems, including…
Character of magnetic excitations in a quasi-one-dimensional antiferromagnet near the quantum critical points: Impact on magneto-acoustic properties
O. Chiatti, A. Sytcheva, J. Wosnitza +5
We report results of magneto-acoustic studies in the quantum spin-chain magnet NiCl-4SC(NH) (DTN) having a field-induced ordered antiferromagnetic (AF) phase. In the vi…
Field-Controlled Magnetic Order in the Quantum Spin-Ladder System (Hpip)2CuBr4
B. Thielemann, Ch. Rüegg, K. Kiefer +18
Neutron diffraction is used to investigate the field-induced, antiferromagnetically ordered state in the two-leg spin-ladder material (Hpip)2CuBr4. This "classical" phase, a conseq…
Hall coefficient and Hc2 in underdoped LaFeAsO0.95F0.05
Y. Kohama, Y. Kamihara, S. Riggs +5
The electrical resistivity and Hall coefficient of LaFeAsO0.95F0.05 polycrystalline samples were measured in pulsed magnetic fields up to m0H = 60 T from room temperature to 1.5 K.…
Ordered magnetic phases of the frustrated spin-dimer compound Ba3Mn2O8
E. C. Samulon, Y. -J. Jo, P. Sengupta +4
Ba3Mn2O8 is a spin-dimer compound based on pairs of S=1, 3d^2, Mn^{5+} ions arranged on a triangular lattice. Antiferromagnetic intradimer exchange leads to a singlet ground state…
