Popis:	A new type of magnetoresistance characterized by its anomalous field dependence has been found in artificially multilayered ferrimagnets of Fe/Gd and of modified double‐structured {Fe/Gd}/{Fe/Gd}. The anomaly is attributed to the spin‐flop which remarkably takes place at fields less than 1 kOe even at room temperature and is particularly pronounced in the double‐structured multilayers. In coincidence with the spin‐flop, the magnetoresistance shows an up and down change against field.
