摘要： Provided are a data transmission device and a data transmission method, which are applied to a field of an information technology. The data transmission device includes: a signal conversion module (30) and a signal transmission module (20), wherein the signal conversion module (30) is configured to convert, at a data transmitting end, an electrical signal containing a data information into a magnon signal containing the data information; the signal transmission module (20) is configured to transmit the magnon signal containing the data information to a data receiving end; and the signal conversion module (30) is further configured to convert, at the data receiving end, the magnon signal containing the data information into the electrical signal containing the data information. The data transmission method includes transmitting the data by using the magnon signal, and no voltage or current is required in a process of transmitting the data.

摘要： The present disclosure relates to the technical field of information data storage and processing. There is provided a method for regulating magnetic multi-domain state, comprising: when a current is applied to a magnetic thin film, applying an additional external magnetic field having a magnetic field strength of 0 to 4×105 A/m to regulate magnetization state of the magnetic thin film; wherein the current is configured to drive movements of a magnetic domain of the magnetic multi-domain states in the magnetic thin film, and the external magnetic field is configured to regulate generation of new magnetic domain in the magnetic thin film and state of the magnetic domain during the movement, so that the magnetic thin film is in a stable magnetic multi-domain state. Such a multi-domain state can't be affected by a higher or lower current and keeps stable when the current is removed. Such a method may be used for magnetic memory or spin-logic device to implement a nonvolatile multi-valued storage, multi-bits logic operation, or neuromorphic computing.

Such a method may be used for current magnetic memory and to operate the magnetization stage of the spin-logic device in the future to implement a nonvolatile multi-valued storage and multi-bits logic operation.
