| Abstract: | From magnetic susceptibility measurements we have determined the ordering temperature TC of ferromagnetic (CH3NH3)2CuC?4 as a function of hydrostatic pressure up to P ～ 11 kbar. The increase of TC, ～ 30% for ～ 11 kbar, is roughly quadratic with P. The data are discussed in terms of the P-dependence of the effective interlayer exchange field HÉ. |
