Description

The proposed device relates to the region :: CT1 auxiliary technology and can be used in memory devices, in which 3 cylindrical domains are used as information carriers. The promotion of magnetic cylindrical domains in a magnetically uniaxial material is accomplished by 1UD by the action of gradient magnetic fields created by ferromagnetic materials; prn their magnetization in p, not 11 :; The field is rotating in the ILOSKO.STY of the crystal plate. Ferromagnetic propulsive announcements usually have a T- or Y-shaped and rectangular configuration. A device for generating cylindrical magnetic domains and introducing them into the propulsive channel is known. Such a device contains a storage element for the HijTHoro domain with a reverse magnitude of the magnetization in the crystal plate. The magnetic domain storage element is formed by the ferromagnetic application of a magnet of a soft material placed on the surface of a crystal plate. The generation of C1 of the cylindrical domain in such a device is carried out by stretching the magnetic domain, p pg; 1 cc, egos along the perimeter of the ferromagnetic application of the storage element in the outer magnet; field, followed by splitting it into two domains, one of which is cylindrical, is introduced into the channel, and the second continues its movement along the element application; pai; eHini and can be used to generate a cylindrical domain in the next cluster. Outside, the control magnetic field rotates in the plane of the plane. kr11stalla. However, the known; 1st device has the following disadvantages; when moving along the perimeter of the storage element, the magnetic element undergoes an action of the frictional force, which leads to a delay in the movement of the magnetic domain from the control field; mn, as a result, to a speed limitation of such a device: x fields larger than the floor are needed; for ph advancement that requires consumption; additional: m1:; post and hope; the operation of the entire device. Purpose; The invention is an increase in the speed and reliability of operation of the generator of cylindrical magnetic domains. The essence of the invention is that a ferromagnetic application made of magnetically hard material is used as a storage element of the magnetic domain, placed 3 pas on the surface of the crystal. Such an application, once magnetized, will hold the magnetic domain at one of the ends. The use of magnetic hardness storage allows you to store the magnetic domain without consuming any energy and improve the speed of the device, since it eliminates the movement of the magnetic domain along the perimeter of the storage element. The magnetic domain splitting element is made in the form of a compressed conducting loop through which a pulsed current is passed. FIG. 1-3 illustrate various options for the formation of cylindrical magnetic domains by the proposed generator. The proposed generator of magnetic cylindrical domains consists of a plate of a magnetically uniaxial crystal /, on the surface of which are placed appl katsp 2 of magnetically rigid material, the element 3 of the magnetic domain spacing, made in the form of a conductive loop n located at the end of the magnetically soft application, where the magnetized domain and the rotating loops are held appliqué 4 of magnet of ductile material. The work of the generator can be represented as follows. In its entire magnetic field, perpendicular to the plane of the plast crystal, the magnetic domain is held at the edge of the ferromagnetic application from a magnetic material, because a magnetic pole was created for it at this edge of the application 2 (Fig. 1). When the Poison control field (Fig. 2) is directed, on the edge of the soya, days with the application 2 of the propulsion 4, an ion pole is created that attracts the magnetic field.

4 dope At this moment, an impulse current is passed through the conductive loop of element 3, the envelop of the magnetic domain, the magnet field of which causes the magnetic domain to split into two; of these, cylindrical, is introduced into the advance diagram (Fig. 3). In the absence of an impulse, it is in the irozdal; loop generation and entry of the central indirectional domain into the advanced scheme is not necessary. The proposed device has the following advantages: for storing a magnetic domain, iodine application of a generator does not require its movement along its perimeter in an external magnetic field; the generation of a cylindrical domain is carried out, like its movement, in a single control field. These advantages allow to increase the speed and reliability of refiepaTOpa operation of cylindrical magnetic houses. The generator of cylindrical magnetic domains containing a plate of a magnetically uniaxial crystal with a magnetic domain storage element with a reverse magnetization direction and a splitting element of the magnetic domain, which is in the form of a current-carrying loop located above the reverse direction of magnetization, characterized in that, in order to increase the operation and reliability of the device, the specified element of the stored magnetic house on applique it is in the form of hard magnetic material, HA, magnicheiioy in the plane of the plate.
