## It is shown, from the spln-polarlzed total-energy band-structure calculation, that the antlferromagnetlc insulating state is stable against the paramagnetlc metalllc state for LazCu04, and that holes appear in the Cu dx2-y2 band and then In the Cu d=2 band upon doping of Sr.
The magnetic susceptibility × of La 2 xSrxCu04 was measured in the range x=O.06 to 0.3. The Tdependent part xs(T) of X below x~O.18 ~onsists of a term X~(T) arising from antiferromagnetically correlated Cu-spins, while xS(T) above x=O.18 consists of x~(T) and a Curie term which is small but grows wi
