This research work focuses on analyzing how titanium substitution in site B affects the physical characteristics of La067Ba0.22Sr0.11Mn0.95Ti0.05O3. Experimental characterization was used to establish magnetic measurements and specific heat measurements for this solid–solid combination. Following magnetic measurements and those of specific heat under a magnetic field applied around TC, the magnetocaloric characteristics of this system were taken into consideration. Both the TC transition temperature and the entropy variation produce comparable findings. The variation of the adiabatic temperature was estimated from the variation of the magnetic entropy and the specific heat. Additionally, the doping reduces the magnetocaloric characteristics of our compound, as evidenced by the relative cooling power, which is regarded as a crucial metric for magnetic refrigeration. The power law for the adiabatic temperature was used to calculate the values of b and p. Additionally, the values of the local exponent n that we calculated from the critical exponents are smaller than those obtained from the power law (|ΔS (H)| ∞ Hn). We discovered that αpure is negative (disorder is irrelevant) by applying the Harris criterion. These results support that disorder has no significant effect on critical exponents and universality class. Besides, by calculating the variance σ2 and following the rules of selection of the universality class according to the value of σ, we found that the critical exponents of our system belong to the mean field model. This indicates that Ti-doping changes the universality class of this kind of manganite perovskites. Finally, a comparison between the magnetocaloric effects of two compounds (father and the studied compound) was undertaken to develop a single sample with a significant magnetocaloric effect.
