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…
Magnon spectrum of the helimagnetic insulator Cu2OSeO3
P. Y. Portnichenko, J. Romhanyi, Y. A. Onykiienko +11
Complex low-temperature ordered states in chiral magnets are typically governed by a competition between multiple magnetic interactions. The chiral-lattice multiferroic Cu2OSeO3 be…
Momentum-space structure of quasielastic spin fluctuations in Ce3Pd20Si6
P. Y. Portnichenko, A. S. Cameron, M. A. Surmach +8
Among heavy-fermion metals, CePdSi is one of the heaviest-electron systems known to date. Here we used high-resolution neutron spectroscopy to observe low-energy mag…
