The magnetization avalanches under field have been investigated at low temperature in Pr0.50Ca0.50Mn1-xNixO3 (x=0.05). In zero field, a 5% of Ni at the Mn site provokes the coexistence of three types of magnetic/structural mesoscopic domains at low temperature: ferromagnetic metallic (majority phase), pseudo-CE and CE-type (minority phase). The ultrasharp steps observed in the low-temperature isothermal magnetization and resistivity curves were investigated by neutron powder diffraction in magnetic fields up to 5 T. At 3 T an abrupt growth of ferromagnetic microclusters occurs at the expenses of the two types of antiferromagnetic orbital-ordered domains (CE and pseudo-CE regions). [ABSTRACT FROM AUTHOR] |
