In the initial BiFeO3 composition there is an incommensurate spatial spin-modulated cycloidal structure (SSMS), which prevents the applied use of the multiferroic properties[1,2]. For several decades, various experiments have been carried out to suppress SSMS. Doping of bismuth ferrite makes it possible to expand the possibilities of its practical application due to its multiferroic properties[3]. Partial substitution of strontium atoms for bismuth atoms leads to a noticeable change in its properties and SSMS modification[4]. Using 57Fe zero-field NMR, we were able to observe the modification of SSMS in the Bi1-xSrxFeO3 series for x = {0.035; 0.07; 01; 0.14} at 4.2 K up to its destruction and draw conclusions about the effect of heterovalent substitution of Bi3+ with Sr2+ on the anharmonicity parameter. XRD and magnetic measurements were carried out to observe the evolution of magnetic properties and structure of the samples of the series.
