We report on a pronounced magnetic anisotropy of magnetically doped quasi-two-dimensional charge density wave (CDW) Nb Se2 at doping concentrations near 1%, and on temperature dependent reflectance, both phenomena above Nb Se2 superconducting transition (7.2 K). Unusual spikes in magnetization reversal are noticeable near 20 K, below the CDW transition (33 K), and disappear as temperature nears the superconducting transition. In the far infrared region of the spectrum, we find two sudden jumps in reflectivity, one near the CDW transition, the other near 18 K. This second increase in reflectivity combined with unusual magnetization reversal is potentially indicative of an additional order parameter in the system, possibly a mixed state of the CDW and a spin density wave, or, alternatively, it represents a far infrared signature of dramatically altered quasiparticles scattering near 20 K. © 2008 American Institute of Physics.
