Using the mean-field and ferromagnetic spin-wave theory at low temperatures, total exchange integrals and Curie temperatures are calculated in the range 0 <= x <= 0.2. Calculated values of T,, are in good agreement with those obtained by magnetic measurements. In addition, the total exchange integral decrease with Bi3+ shows the existence of canted ferromagnetic order in the samples, as observed in experimental results.eninfo:eu-repo/semantics/closedAccessmanganitesexchange interactionspin waveCurie temperaturemean-field theoryBi dopingArticle19274115412310.1142/S02179792050326192-s2.0-27544490711Q3WOS:000233315500008Q4
