Abstract
Recently from our group, we reported giant exchange bias value of 5.5 kOe at 5 K in a quasi-two-dimensional single layered polycrystalline Ruddlesden-Popper (RP) compound SrLaCo0.5Mn0.5O4. Here, a detailed temperature dependent Raman and dielectric spectroscopic studies are carried out on SrLaCo0.5Mn0.5O4 to understand the spin-phonon coupling and dielectric properties, respectively. A strong spin-phonon coupling constant of λ = 2.72 cm−1 is evident which is associated with Mn/Co‒O bonds. A large dielectric constant of ε' = 2904 at 1 kHz frequency at 297 K is found in this system. Data availabilityThe data that supports the findings of this study are available within the article [and its supplementary material]. Please see supplementary material for details of the impedance spectroscopy analysis.
