This is the case for La_{2-x}Sr_{x}NiO_{4+δ}, in which coupled incommensurate charge and spin stripes form at low temperatures. Here, we use resonant x-ray photon correlation spectroscopy to study the temporal stability and domain memory of the charge and spin stripes in La_{2-x}Sr_{x}NiO_{4+δ}. Although spin stripes are more spatially correlated, charge stripes maintain a better temporal stability against temperature change. More intriguingly, charge order shows robust domain memory with thermal cycling up to 250 K, far above the ordering temperature. These results demonstrate the pinning of charge stripes to the lattice and that charge condensation is the predominant factor in the formation of stripe orders in nickelates. date: 2021-04-30 date_type: published official_url: https://doi.org/10.1103/PhysRevLett.126.177601 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1866115 doi: 10.1103/PhysRevLett.126.177601 lyricists_name: Robinson, Ian lyricists_id: IKROB22 actors_name: Robinson, Ian actors_id: IKROB22 actors_role: owner full_text_status: public publication: Physical Review Letters volume: 126 number: 17 article_number: 177601 citation: Shen, Y; Fabbris, G; Miao, H; Cao, Y; Meyers, D; Mazzone, DG; Assefa, T; ...
