Magnetic Field resulting from non-linear electrical transport in single crystals of charge-ordered Pr${}_{0.63}$ Ca${}_{0.37}$ MnO${}_3$}

Abstract

In this letter we report that the current induced destabilization of the charge ordered (CO) state in a rare-earth manganite gives rise to regions with ferromagnetic correlation. We did this experiment by measurement of the I-V curves in single crystal of the CO system Pr${}_{0.63}$Ca${}_{0.37}$MnO${}_3$ and simultanously measuring the magnetization of the current carrying conductor using a high T${}_c$ SQUID working at T = 77K. We have found that the current induced destabilization of the CO state leads to a regime of negative differential resistance which leads to a small enhancement of the magnetization of the sample, indicating ferromagnetically aligned moments.
