Muon-spin-rotation (μSR) measurements under hydrostatic pressures in Tl(Cu1-xMgx)Cl3. with x = 0.015 were carried out in order to investigate the reported crossover from impurity-induced phase to pressure-induced phase. The spontaneous muon-spin-rotation, which indicates the existence of a long-range coherent order, is observed under pressures in zero field. With decreasing temperature in 3.1 kbar, the internal static magnetic field Hint saturates to 280 gauss, however, with increasing pressure at 2.3 K, Hint saturates to 320 gauss. This discrepancy suggests a new phase inside the ordered phase in the phase diagram.
