High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr1-xCax VO3 (0
Amer Physical Soc2016Single crystals of superconducting SmFeAsOHx: Structure and properties
László Forró, Alla Arakcheeva, Richard Gaal, Janusz Andrzej Karpinski, Andrea Pisoni, Sergiy Katrych, Ping Huang, Péter Krisztián Matus
We report the synthesis, structure, and superconducting properties of single crystals of SmFeAsOHx. The crystals were grown at high pressure and high temperature using a cubic anvil technique. H-1-NMR studies confirm the presence of H atoms in the samples. ...
Amer Physical Soc2016Direct observation of anisotropic magnetic field response of the spin helix in FeGe thin films
Henrik Moodysson Rønnow, Jonathan White
We report the observation by small-angle neutron scattering (SANS) of a magnetic helical structure confined in a thin film of the chiral lattice magnet FeGe. Twofold magnetic Bragg spots appearing below the magnetic transition temperature indicate the form ...

We report a study of the electrical transport properties of single crystals of Pr(4)Fe(2)As(2)Te(1-)xO(4), a recently discovered iron-based superconductor. Resistivity, Hall effect, and magnetoresistance are measured in a broad temperature range revealing ...
Amer Physical Soc2016Evolution of the charge density wave superstructure in ZrTe3 under pressure
Corsin Battaglia, Helmuth Berger, Philipp Aebi
The material ZrTe3 is a well-known example of an incommensurate periodic lattice distortion (PLD) at low temperatures due to a charge density wave (CDW). Previous studies have found a sharp boundary as a function of pressure between CDW below 5 GPa and bul ...

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser
We study the coexistence of strain-and charge-mediated magnetoelectric coupling in a cobalt (0-7 nm) wedge on ferroelectric (011)-oriented Pb(Mg-1/3/Nb-2/3)O-3-PbTiO3 using surface-sensitive x-ray magnetic circular dichroism spectroscopy at ...
Amer Physical Soc2016Magnetic model in multiferroic NdFe3(BO3)(4) investigated by inelastic neutron scattering
We performed inelastic neutron scattering measurements on single crystals of NdFe3((BO3)-B-11)(4) to explore the magnetic excitations, to establish the underlying Hamiltonian, and to reveal the detailed nature of hybridization between the 4f and 3d magneti ...
2015Torque magnetometry study of magnetically ordered state and spin reorientation in the quasi-one-dimensional S=1/2 Heisenberg antiferromagnet CuSb2O6
The antiferromagnetically ordered state of the monoclinic quasi-one-dimensional S = 1/2 Heisenberg antiferromagnet CuSb2O6 was studied combining torque magnetometry with a phenomenological approach to magnetic anisotropy. This system is known to have a num ...
