Shape-Memory Nanocomposites with Magnetically Adjustable Apparent Switching Temperatures The apparent switching temperatures (T(sw),(app)) that need to be exceeded by the environmental temperature (T(env)) to initialize a shape-memory effect (SME) in magnetosensitive dual- or triple-shape composites are systematically adjusted by application of a constant weak alternating magnetic field. This adaptation of T(sw),(app) is fully reversible and results from the combination of environmental and inductive heating.
