High pressure study of BaFe2As2 - role of hydrostaticity and uniaxial stress (2009)
Duncan, W. J., Welzel, O. P., Harrison, C., Wang, X. F., Chen, X. H., Grosche, F. M., ...
We investigate the evolution of the electrical resistivity of BaFe2As2 single crystals with pressure. The samples used were from the same batch grown from self flux and showed properties that were...
Niklowitz, P. G., Pfleiderer, C., Keller, T., Vojta, M., Mydosh, J. A.
We report simultaneous measurements of the distribution of lattice constants and the antiferromagnetic moment in high-purity URu2Si2, using both Larmor and conventional neutron diffraction, as a...
Topological Hall effect in the A-phase of MnSi (2009)
Neubauer, A., Pfleiderer, C., Binz, B., Rosch, A., Ritz, R., Niklowitz, P. G., ...
Recent small angle neutron scattering suggests, that the spin structure in the A-phase of MnSi is a so-called triple-$Q$ state, i.e., a superposition of three helices under 120 degrees. Model...
Unconventional resistivity at the border of metallic antiferromagnetism in NiS2 (2006)
Niklowitz, P. G., Steiner, M. J., Lonzarich, G. G., Braithwaite, D., Knebel, G., Flouquet, J., ...
We report low-temperature and high-pressure measurements of the electrical resistivity \rho(T) of the antiferromagnetic compound NiS_2 in its high-pressure metallic state. The form of \rho(T)...
Knebel, G., Boursier, R., Hassinger, E., Lapertot, G., Niklowitz, P. G., Pourret, A., ...
We present detailed measurements of the electrical resistivity and microcalorimetry under magnetic field and high pressure which confirm the proximity of YbRh2Si2 to a quantum critical point at...
Field-induced non-Fermi-liquid resistivity of stoichiometric YbAgGe single crystals (2005)
Niklowitz, P. G., Knebel, G., Flouquet, J., Bud'ko, S. L., Canfield, P. C.
We have investigated hexagonal YbAgGe down to 70 mK by measuring the magnetic-field and temperature dependence of the resistivity rho of single crystals in fields up to 14 T. Our results extend the...
An inelastic neutron scattering study of single-crystal heavy-fermion YbAgGe (2005)
Fåk, B, McMorrow, D F, Niklowitz, P G, Raymond, S, Ressouche, E, Flouquet, J, ...
Spin-fluctuation dominated electrical transport of Ni3Al at high pressure (2004)
Niklowitz, P. G., Beckers, F., Lonzarich, G. G., Knebel, G., Salce, B., Thomasson, J., ...
We present the first study of a magnetic quantum phase transition in the itinerant-electron ferromagnet Ni3Al at high pressures. Electrical resistivity measurements in a diamond anvil cell at...
Inelastic neutron scattering study of single crystal heavy fermion YbAgGe (2004)
Fak, B., McMorrow, D. F., Niklowitz, P. G., Raymond, S., Ressouche, E., Flouquet, J., ...
Single crystals of the heavy-fermion compound YbAgGe have been studied by neutron scattering. The magnetic ordering occurring below T1=0.5 K is characterized by a commensurate propagation vector...
