Abstract
Magnetoelastic stress measurements in Ho/Y and Ho/Lu superlattices wer e performed by using a capacitive cantilever technique. The magnetic p hase diagrams obtained from in-field transitions observed in the stres s isotherms show helical, fan and ferromagnetic phases. At zero-field, the ferromagnetic phase is suppressed in Ho/Y and stabilised in Ho/Lu . Magnetoelastic coupling coefficients corresponding to the breaking o f the cylindrical symmetry of the basal plane have been determined. Su rface magnetostriction is observed for {Ho31Lu19}(50).
