We report an unusual giant linear magnetostrictive effect in the ferrimagnetGd$_{2/3}$Ca$_{1/3}$MnO$_3$ ($T_{c} \approx$80 K). Remarkably, themagnetostriction, negative at high temperature ($T \approx T_{c}$), becomespositive below 15 K when the magnetization of the Gd sublattice overcomes themagnetization of the Mn sublattice. A rather simple model where the magneticenergy competes against the elastic energy gives a good account of the observedresults and confirms that Gd plays a crucial role in this unusual observation.Unlike previous works in manganites where only striction associated with 3$d$Mn orbitals is considered, our results show that the lanthanide 4$f$ orbitalsrelated striction can be very important too and it cannot be disregarded.
