    Based on experiments of both transport and paramagnetic resonance for (La1−xYx)2/3Ca1/3MnO3, the ground state above Tc and possible origins of both insulator–metal transition and colossal magnetoresistance near Tc are discussed. Modeling the system as a network of junctions, each consisting of a paramagnetic region sandwiched between two ferromagnetic domains, a phenomenological expression is proposed for resistance as a function of temperature and magnetic field. We show that the observed transport and magnetotransport phenomena can be quantitatively explained by the present model for the whole temperature range studied. © 2000 American Institute of Physics.

    Abstract: We show that the replacement of Mn with Cu, without any structure change, strongly affects the transport and magnetic behaviors in La 2/3 Ca 1/3 Mn1-xCuxO 3 - δ (x ?0.3). Doping largely shifts the insulator-metal transition towards the low-temperature regime and causes substantial enhancements in both resistance and magnetoresistance near the transition for doping range of x ? 15%, and further doping to x ≥ 20% shows insulating behavior. For 15% doping, the sample shows large magnetoresistances (∼104%) over the whole low temperature range. Magnetization measurement at helium temperature reveals that samples for x ? 10% and ≥ 20% basically show ferromagnetic (FM) and antiferromagnetic (AF) behaviors, respectively, while the 15% Cu doped sample undergoes a metamagnetic transition from AF state to FM state on increasing field. We argue that doping introduces the AF insulating phase into the system, causing unusual transport and magnetic behaviors.
