“…15 For lower temperatures, Ghazi et al report ξ C ⊥ ≈ 165Å and ξ C ≈ 375Å. Hence, despite the uncertainty of our analysis and the rough estimates, which are necessary to separate the linear and the nonlinear contributions to M (B), the resulting ferromagnetic correlation lengths provided by our macroscopic study are in a fair agreement with the charge stripe correlation lengths of recent hard x-ray [15][16][17] and neutron diffraction experiments 9 . In summary, using measurements of the macroscopic magnetisation, we find weak ferromagnetic correlations with a correlation length, which is comparable to that of the charge stripe correlations probed by diffraction techniques.…”

“…[1][2][3] In contrast, in the nickelates the stripe order is more pronounced, which makes its detection much easier. [4][5][6][7] In recent years, stripe correlations in the nickelates have been studied with many different techniques, such as neutron scattering [8][9][10][11][12][13][14] , x-ray diffraction [15][16][17] , thermal conductivity 18 , NMR [19][20][21] , µSR 22 , as well as optical 23 and Raman-spectroscopy 24,25 . Nevertheless, very little is known about the thermodynamic properties of the stripe phase, such as the specific heat and the magnetisation in high magnetic fields.…”

“…6,8,10,12,13,14,15,17,22,23,24,25,26 Charge ordering occurs at a temperature T CO typically 100-200 K depending on doping. Magnetic order occurs at a slightly lower temperature T SO .…”

Charge order, dielectric response, and local structure of La5/3Sr1/3NiO4 system

“…Among the TMOs, the La 2-x Sr x NiO 4 , popularly called nickelates, construct good example of such systems with complex interplay between spin-charge-lattice degrees of freedom [5][6][7][8][9][10][11][12][13][14][15][16] . The nickelates have been studied intensively, however, a substantial amount of work is dedicated to the La 5/3 Sr 1/3 NiO 4 , merely due to the fact that the system appears with robust charge stripe ordering for this doping, making it a suitable system to address various functions of the TMO perovskites.…”
