The authors regret that: 1). The authors regret that they forgot to indicate gratitude for carrying out the Mössbauer spectroscopy experiment for one sample with x = 0.25 at room temperature and for a partial interpretation of the obtained results. The authors express special gratitude and acknowledgments to Jaroslav Kohout and Tomas Kmječ from Joint Laboratory of Mössbauer Spectroscopy, Faculty of Mathematics and Physics, Charles University, 18,000 Prague 8, Czech Republic. 2). In the Table 2 some new data should be added. To the uncertainties of the fitted parameters listed in the Table 2, it should be added the experimental uncertainty – represented by half of the width of the channel corresponding to ~0.02 mm/s for the Isomer Shift (IS) and Quadrupolar Shift (QS) and to ~0.2 T for the Hyperfine Field (Bhf). 3). New Figure should be added. [Figure presented] This should be Fig. 3b. This Figure contains detailed and refined fitting information from the results of the Mössbauer spectroscopy experiment. 4). Three additional References which have been used in fitting and interpretation of obtained results from the Mössbauer spectroscopy experiment should be added:  H. Stepankova, J. Kohout, Z. Simsa, NMR study of Ti-Co, Ti-Mg and Ti substituted hexagonal ferrites with magnetoplumbite structure, J. Magn. Magn. Mater. 104–107 (1992) 411–412. https://doi.org/10.1016/0304–8853(92)90856-j.  H.
