MAGNETIC ORDERING IN RE-ENTRANT (PdFe)Mn STUDIED BY AC SUSCEPTIBILITY AND MAGNETORESISTANCE MEASUREMENTS

The linear and non-linear magnetic response and the low field magnetoresistive anisotropy of re-entrant (=Fe)Mn have been measured near both "candidate" transitions. The concensus of current experimental data is that while the entire magnetic response of a ferromagnet is singular 1 h2 XF (h, t) = t-y.G h tr+@ N + . . .

Non-linear charge transport in polythiophene under high AC field

Complex impedance and conductivity were measured for regioregular poly(3hexylthiophene) (P3HT) at alternating current (AC) voltages using a waveform technique. The waveforms were Fourier transformed from time domain to frequency domain and analyzed at fundamental and higher order harmonic frequencies. It was found that the impedance of the semi-conducting P3HT decreases with increasing electric...
