Erratum to ‘‘Substitution effect of Cr³⁺ on hyperfine interactions, magnetic and optical properties of Sr-hexaferrites’’ [Ceram. Int. 44 (2018) 15995–16004, (S0272884218314603), (10.1016/j.ceramint.2018.06.033)]

The publisher regrets Fig. 3 part (b) was missing from this published article. The missing Fig. 3(b) is shown below.[Formula presented] The authors also had two additional updates - the Dxrd value for x = 0.8 sample (in Table 1) has been updated to 48.1 nm instead of 83 nm. The corrected Table 1 is shown below. [Table presented] Finally, in section 2.2 the sentence ‘SEM along with EDX, JEOL JSM-6490, was used for both morphology and chemical composition analysis’, the mentioned model should be “FEI Quanta” rather than model “JEOL JSM-6490". The publisher would like to apologise for any inconvenience caused.
