N. Kernavanois, S. Raymond, B. Grenier, E. Ressouche, G. Knebel, J. Flouquet, P. Lejay

Neutron diffraction experiments performed on single crystal of the antiferromagnetic compound CePd2Si2 under applied pressure up to 18 kbar are reported. The magnetic structure and the temperature line-shape of the order parameter do not change with pressure. Anomalous suppression of the magnetic moment is found at high pressure.
