We have investigated effects of applied uniaxial pressure (
) on magnetic phase transitions in a triangular lattice antiferromagnet CuFeO (CFO) and a slightly Ga-substituted compound CuFeGaO (CFGO) with 
= 0.018. We have performed neutron diffraction, spherical neutron polarimetry, magnetic susceptibility and pyroelectric measurements under up to 100 MPa applied on the [1
0] surfaces of the single crystal samples.

In both of CFO and CFGO ( = 0.018), the application of significantly increases the transition temperature from the paramagnetic phase to a collinear incommensurate antiferromagnetic phase. This suggests that the application of breaks equilateral symmetry of the triangular lattice and partially relieves geometrical spin frustration, which generally suppresses long-range magnetic orderings. Thus we demonstrated that uniaxial pressure can be an effective tool to control magnetic phase transitions in frustrated magnets.
