KCuCl and TlCuCl are singlet ground state systems with excitation gap of 31K and 7.7K, respectively. The origin of the spin gap is the strong antiferromagnetic spin dimer of the chemical Cu
Cl
unit. These spin dimers are weakly coupled three dimensionally via non-frustrating inter dimer exchanges. The magnetization measurements under applied hydrostatic pressure show the existence of the magnetic order above certain critical pressure Pc=8.8 kbar and 0.42 kbar, respectively. We report on the elastic neutron scattering results of the pressure induced magnetic ordering in these quantum systems. The observed magnetic structures and the possible role of the spin-lattice coupling in the spin reorientation in TlCuCl3 under pressure will be discussed.
