We have investigated effects of applied uniaxial pressure () on magnetic phase transitions in a triangular lattice antiferromagnet CuFeO $_{2}$ (CFO) and a slightly Ga-substituted compound CuFe $_{1-x}$ Ga $_{x}$ O $_{2}$ (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 [10] surfaces of the single crystal samples.
