Magnetic-field-controlled spin fluctuations and quantum criticality in Sr3Ru2O7
C. Lester, S. Ramos, R. S. Perry +8
When the transition temperature of a continuous phase transition is tuned to absolute zero, new ordered phases and physical behaviour emerge in the vicinity of the resulting quantu…
Role of vibrational entropy in the stabilization of the high-temperature phases of iron
Jürgen Neuhaus, Michael Leitner, Karl Nicolaus +3
The phonon dispersions of the bcc and fcc phases of pure iron (α-Fe, γ-Fe and δ-Fe) at ambient pressure were investigated close to the respective phase transition temperatures. In…
Unexpected phase locking of magnetic fluctuations in the multi-k magnet USb
J. A. Lim, E. Blackburn, N. Magnani +4
The spin waves in the multi-k antiferromagnet, USb, soften and become quasielastic well below the AFM ordering temperature, T_N. This occurs without a magnetic or structural transi…
Evidence of a bond-nematic phase in LiCuVO4
M. Mourigal, M. Enderle, B. Fåk +5
Polarized and unpolarized neutron scattering experiments on the frustrated ferromagnetic spin-1/2 chain LiCuVO4 show that the phase transition at HQ of 8 Tesla is driven by quadrup…
From (pi, 0) magnetic order to superconductivity with (pi, pi) magnetic resonance in Fe1.02(Te1-xSex)
T. J. Liu, J. Hu, B. Qian +17
The iron chalcogenide Fe1+y(Te1-xSex) is structurally the simplest of the Fe-based superconductors. Although the Fermi surface is similar to iron pnictides, the parent compound Fe1…
Highly Dispersive Spin Excitations in the Chain Cuprate Li2CuO2
W. E. A. Lorenz, R. O. Kuzian, S. -L. Drechsler +11
We present an inelastic neutron scattering investigation of Li2CuO2 detecting the long sought quasi-1D magnetic excitations with a large dispersion along the CuO2-chains studied up…
