Incommensurate short-range multipolar order parameter of phase II in Ce3Pd20Si6
P. Y. Portnichenko, S. Paschen, A. Prokofiev +5
The clathrate compound Ce3Pd20Si6 is a heavy-fermion metal that exhibits magnetically hidden order at low temperatures. Reputedly, this exotic type of magnetic ground state, known…
Impurity effects on spin dynamics in magnetic and superconducting iron pnictides and chalcogenides
M. A. Surmach, P. Y. Portnichenko, J. T. Park +5
In this paper we summarize the effects of magnetic and nonmagnetic impurities on the spin dynamics in Febased superconductors and their parent compounds. The effects of chemical su…
Non-collinear antiferromagnetism of coupled spins and pseudospins in the double perovskite La2CuIrO6
Kaustuv Manna, R. Sarkar, S. Fuchs +19
We report the structural, magnetic and thermodynamic properties of the double perovskite compound La2CuIrO6 from X-ray, neutron diffraction, neutron depolarization, dc magnetizatio…
Magnetic field dependence of the neutron spin resonance in CeB6
P. Y. Portnichenko, S. V. Demishev, A. V. Semeno +12
In zero magnetic field, the famous neutron spin resonance in the f-electron superconductor CeCoIn5 is similar to the recently discovered exciton peak in the non-superconducting CeB…
Magnetic phase diagram of the helimagnetic spinel compound ZnCr2Se4 revisited by small-angle neutron scattering
A. S. Cameron, Y. V. Tymoshenko, P. Y. Portnichenko +7
We performed small-angle neutron scattering (SANS) measurements on the helimagnetic spinel compound ZnCr2Se4. The ground state of this material is a multi-domain spin-spiral phase,…
