Quadratic heat capacity and high-field magnetic phases of V5S8
C. A. Sonego, P. M. T. Vianez, H. Li +4
We report the observation of an unexpected quadratic temperature dependence of the heat capacity in the vanadium sulphide metal V5S8 at low temperatures which is independent of app…
Understanding the complex phase diagram of uranium: the role of electron-phonon coupling
S. Raymond, J. Bouchet, G. H. Lander +8
We report an experimental determination of the dispersion of the soft phonon mode along [1,0,0] in uranium as a function of pressure. The energies of these phonons increase rapidly…
Fermi Surface of Alpha-Uranium at Ambient Pressure
D. Graf, R. Stillwell, T. P. Murphy +10
We have performed de Haas-van Alphen measurements of the Fermi surface of alpha-uranium single crystals at ambient pressure within the alpha-3 charge density wave (CDW) state from…
On the nature of the phase transition in the itinerant helimagnet MnSi
S. M. Stishov, A. E. Petrova, S. Khasanov +5
A careful study of thermodynamic and transport properties of a high quality single crystal of MnSi at ambient pressure suggests that its transition to a helical magnetic state near…
Inversion symmetry breaking in noncollinear magnetic phase of a triangular lattice antiferromagnet CuFeO2
T. Kimura, J. C. Lashley, A. P. Ramirez
Magnetoelectric and magnetoelastic phenomena correlated with a phase transition into noncollinear magnetic phase have been investigated for single crystals of CuFeO2 with a frustra…
Catastrophic Fermi surface reconstruction in the shape-memory alloy AuZn
P. A Goddard, J. Singleton, R. D. McDonald +4
AuZn undergoes a shape-memory transition at 67 K. The de Haas van Alphen effect persists to 100 K enabling the observation of a change in the quantum oscillation spectrum indicativ…
