Using spectroscopic and visual optical methods the shift of the critical temperature (Ttr~42K) of the first-order phase transition of the Jahn-Teller type to the lowtemperature side at doping the CsDy(MoO4)2 crystal with Bi3+ (concentration up to x~0.08) was revealed. Effect of the doping is compared to the effect of uniaxial pressure. Using the result of the Zeeman effect we have calculated the critical value Hc of external magnetic field at which the spontaneous change of the sizes of crystal is suppressed under magnetic field and the high-temperature phase may be induced at T=0°K. It is supposed that doping with Bi3+ leads to decrease of the critical magnetic field value for doped CsDy(MoO4)2 .
