Magnetostriction and magnetization M of Tb2(MoO4)3 samples are measured at temperatures T = 4.2 and 20 K in fields H up to 14 T directed along the polar axis . Results of the magnetostriction measurements obey the first law of thermodynamics: -MH = TΔS - WE, where ΔS is the change of the entropy and WE is the work of internal electric field done when ions move due to the magnetostriction.
