Abstract
This device comprises an ionically implanted magnetic garnet layer, in which are defined non-implanted patterns and an electrically conductive layer superimposed on the garnet layer and insulated therefrom. The patterns are islands which are separated from one another. The electrically conductive layer has a first conductive coating having windows parallel to the first direction for respectively displacing the bubbles located between the patterns of the first pairs of patterns arranged parallel to a first direction, by a pulse-type current parallel to a first direction. The electrically conductive layer also has a second conductive coating superimposed on the first conductive coating and insulated therefrom and which has windows parallel to a second direction in order to respectively displace the bubbles between the patterns of the second pairs of patterns arranged parallel to a second direction, by a pulse-type current parallel to a second direction. Each first pair of patterns has a common pattern with each second pair of patterns.
