We estimated the photon-pseudoscalar particle mixing constant from the effectof cosmological alignment and cosmological rotation of polarization plane ofdistant QSOs. This effect is explained in terms of birefringent phenomenon dueto photon-pseudoscalar (axion-like) particle mixing in a cosmic magnetic field.On the contrary, one can estimate the strength of the cosmic magnetic fieldusing the constraints on the photon-axion-like particle coupling constant fromthe CAST experiment and from SNe Ia dimming effect. In a result, the lowerlimit on the intergalactic ($z\approx 1\div 2$) magnetic field appears at thelevel of about $4\times 10^{-10}\div 10^{-11}$ G.
