A Model for the Pr1-xCaxMnO3 Series with x = 0.30-0.50 under Application of Weak Magnetic Fields

We introduce a proposal for explaining manganites behavior, in the Pr1-xCaxMnO3 series with x=0.30-0.50. We carry out computer simulations for the Oguchi model along with the crystal field contribution. We contrast the outcomings to experimental measurements made with a commercial magnetometer SQUID. For analyzing the magnetization drop at low temperatures, we take into account quasi-probability distributions.
