The crystal field model of Akselrad and Callen is used to estimate the contribution of Fe ions to the growth‐induced non‐cubic magnetostriction of rare‐earth iron garnets. The effect is predicted to be significantly smaller than the previously calculated non‐cubic magnetostriction due to rare‐earth‐site ordering. The estimate uses a feature of the model which renders the local magnetoelastic tensor symmetric in strain and spin components. A plausible argument is adduced to support the conclusion independently of the model.
