It is shown that consideration of harge density wave (CDW) in addition to spin density wave (SDW) allows for the better explanation of the new experimental results.

Optical Dichroism

We propose here that the pseudogap phase of high Tc superconductors is probably unconventional spin density wave (USDW). We present our analysis on the angular dependent magnetoresistance (ADMR) in the pseudogap phase which should be accessible experimentally. Also this result applies also to the AF phase of URu2Si2. We show that this model is consistent with the optical dichroism seen by ARPES.

Density Wave Theory

We proposed earlier possible temperature-induced ferromagnetism (TIF) in TiBe 2, TiBe 2−x Cu x and other itinerant magnets. The value of the critical field H cr for the existence of TIF in TiBe 2, evaluated on the basis of our and others’ experimental results, coincide with the value H cr ≅610 G predicted by Enz within the spin density wave theory of itinerant antiferromagnetism (AFM). The possibilities of the existence in TiBe 2 of the TIF mechanism of spin fluctuations around the AFM mode as predicted by Moriya, and of the temperature-induced noncompensated itinerant AFM, i.e., ferromagnetism, are considered.
