We have investigated the magnetic and transport properties ofPr$_{0.65}$Ca$_{0.35}$MnO$_3$ and Pr$_{0.82}$Na$_{0.18}$MnO$_3$ with almostsame doping level under various magnetic fields. Upon applying a field of 4 T,both compounds undergo a metamagnetic transition from antiferromagnetic (AFM)to ferromagnetic (FM) in the low temperature region. The field-induced FM stateis very stable for at least 10$^5$ s even after removing the field. Thisirreversible FM behavior is different from the spontaneous FM ordering as wellas the FM state in a reversible metamagnetic transition. We discuss thisunusual FM phenomenon found in the Pr-doped manganites with the AFM groundstate in terms of the reorientation of Mn spins pinned by localized Pr moments.Comment: 19 pages, 8 figure, in press in Phys. Rev.
