A correlation of phase diagrams with sharp jumps of the magnetization, which were previously observed upon magnetic-field-induced AFM-FM transition, has been studied for a number of low-bandwidth manganites. This transition was shown to proceed in milliseconds and is connected to a spontaneous heat avalanche, but mechanisms responsible for an origin and a development of the avalanche are still unclear. Different manganites (Pr<sub>0.67</sub>Ca<sub>0.33</sub>MnO<sub>3</sub>, Sm<sub>0.55</sub>Sr<sub>0.45</sub>Mn<sup>18</sup>O<sub>3</sub>, Eu<sub>0.58</sub>Sr<sub>0.42</sub>MnO<sub>3</sub>) are shown to characterize by a qualitatively identical phase diagram, with the slope of the AFM-FM boundary in the H-T-plane being negative, that is probably guides the avalanche-like character of the transition. |
