description The invention refers to the field of electronics and is provided for the manufacture of storage commutation devices, utilized in computer and commutation engineering. The device contains a base of Pb, onto which there are successively deposited a layer, absorbing the acoustic surface waves, a barrier layer of superconducting ceramics YBa2Cu3O7 and a controlling layer of piezocrystal GaAs, in the centre of which it is deposited an anti-pin converter of Cr-Al, between the barrier and the controlling layers being deposited contacts ofCr-Cu. The contacts of Cr-Cu are placed around the edges of a circumference and consist of longitudinal contacts, placed along the c crystallographic axis of the compound YBa2Cu3O7, which coincide with the propagation direction of the acoustic surface waves; transversal contacts, placed perpendicular to the crystallographic axis of the compound YBa2Cu3O7, which are perpendicular to the propagation direction of the acoustic surface axis; intermediate contacts, placed around the edges of the circumference between the longitudinal and the transversal contacts.Claims: 1Fig.: 2
