We examine the NMR experimental data for the normal state of YBa2Cu3OT-8 within the Fermi-liquid approach. We explain the temperature dependence of the Knight shift as well as 170 (S9y) relaxation rate in "underdoped" (To = 60K) compound as stemming from a strong variation of the density of states (
Magnetization measurements on high-quality YBa2Cu30 = single crystals are analyzed according to the model of Hao and Clem. The resulting thermodynamic critical field and the jump in the specific heat at To, calculated from it, increase monotonically as the oxygen content is increased, even up to x =
