Multiple crossovers between positive and negative magnetoresistance versus field due to fragile spin structure in metallic GdPd₃.

ABSTRACT: Studies on the phenomenon of magnetoresistance (MR) have produced intriguing and application-oriented outcomes for decades-colossal MR, giant MR and recently discovered extremely large MR of millions of percents in semimetals can be taken as examples. We report here the discovery of novel multiple sign changes versus applied magnetic field of the MR in the cubic intermetallic compound GdPd₃. Our study shows that a very strong correlation between magnetic, electrical and magnetotransport properties is present in this compound. The magnetic structure in GdPd₃ is highly fragile since applied magnetic fields of moderate strength significantly alter the spin arrangement within the system-a behavior that manifests itself in the oscillating MR.
