Abstract-Electrical transport properties of (La,Pr,Ca)MnO3 nanowires investigated using terahertz time domain spectroscopy
The electrical of a 100-nm-width (La,Pr,Ca)MnO sample were investigated using terahertz (THz) time domain When the of incident THz pulses was parallel to the we obtained their intrinsic THz conductivity. The temperature-dependent conductivity and metallic fraction were simultaneously estimated by analyzing the THz conductivity using a The evaluated conductivity closely reproduced that measured by electrical probe measurement. The metallic fraction showed the evolution of electric domains from the metallic state at temperatures below 100 K to the insulating state at temperatures above 150 K through a coexistence region, which was in consistence with the phase-separated scenario.
