โฆ Synopsis
We present neutron scattering data which indicate that the local structure of La~CuO4 in the LTO phase is disordered. Data from two different diffractometers are compared and systematic differences between the pair distribution functions (PDF) of the LTO model and the data are reproduced in both cases.

The failure of the local spin density approximation to describe the antiferromagnetic ground atatc of La,CuO, is analyzed. It is argued that it is a general feature of the LDA to underestimate the tendency towards an AF ground state in transition-metal oxide compounds. From the LSD-RPA spin suscep
