Magnetization reversal in for three different temperatures. Linear paramagnetic background has been subtracted from all three curves.
Comparison of hysteresis curves for Mn-, Fe-, and Cr-doped . The curve for Cr-doped sample is scaled up. The inset shows the M vs H field sweep for the undoped sample.
(a) Reflectance spectra for in the far infrared portion of the spectrum for a variety of temperatures. Shaded areas are not used for the analysis in this report, as they originate from low sensitivity of the detector in the narrow ranges marked in the plot. (b) Temperature dependence of reflectance, obtained by slicing data from panel (a) with two jumps comparable in magnitude.
Reflectance spectra for temperatures bracketing the CDW and a suggested SDW transition (color curves), and the results of Drude-like model (full, black curves). The inset shows a detail of a phonon replica near .
