Abstract

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 [001]. Results of the magnetostriction measurements obey the first law of thermodynamics: -MH = TΔS - W_E, where ΔS is the change of the entropy and W_E is the work of internal electric field done when ions move due to the magnetostriction.
