Phonons and magnons in stripe-ordered nickelates. A Raman scattering study
Electronic correlation effects in La₂-xSrxNiO₄ (x = 1/3 and 0.225) lead to spontaneous phase
 separation into microscopic spin/charge stripes with commensurate and incommensurate order, respectively.
 Raman scattering experiments on such single crystalline materials show a rich phe...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Electronic correlation effects in La₂-xSrxNiO₄ (x = 1/3 and 0.225) lead to spontaneous phase
separation into microscopic spin/charge stripes with commensurate and incommensurate order, respectively.
Raman scattering experiments on such single crystalline materials show a rich phenomenology
of phonon and magnon anomalies due to the new, self-organized periodicities. These effects
are observable as function of temperature but can also be induced by cooling in a seemingly
small magnetic field leading to a reorganization of stripe structure.
