ResumoTemperature dependence of the parameter of the unit cell of Gd3Fe5O12 was measured in the 80–450 K range. A special emphasis was placed on the vicinity of the compensation point Tcomp≈290K. The dilatation coefficients for both low and high temperature phases are obtained. A jump in the lattice parameter of approximately 0.003 Å is clearly visible at Tcomp. Two observed anomalies at approximately Tcomp −23 K and Tcomp + 23 K correspond to the boundaries of the low and high temperature phases in the magnetic phase diagram.
