We present experimental results of the Nernst-effect in the normal state of various superconductors. In particular, we investigated the high temperature superconductor La2SrxCuO4 with and without Eu-doping. The Eu-ions suppress superconductivity and stabilize a stripe phase in the CuO2-planes of the materials. We find that the relatively large Nernst-coefficient which has previously been reported for the normal state in pure La2SrxCuO4 is also present in the Eu-doped materials extending deep into the stripe ordered phase. We compare these results with the Nernst-effect of the superconductor YNi2B2C.
