MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202641123222 A) filed by Indian Institute Of Technology Hyderabad on October 14, 2026, for Skyrmionium-Based Logic Gate Device And A Method Of Performing Logic Functions Using The Device.
Inventors include Srilalitha Gajarao; Arabinda Haldar; and Chandrasekhar Murapaka.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present disclosure relates to a skyrmionium-based logic gate device (100) and a method of performing logic functions using the device (100). The device (100) comprises a magnetic layer (102) and an adjacent heavy metal layer (104). A plurality of input nanotracks (106), comprising a first nanotrack (106A), a second nanotrack (106B), and a third nanotrack (106C), convey respective skyrmioniums towards an interaction region (108) facilitating their interaction. A voltage control unit (110) applies a voltage to voltage-controlled gate (VCG) (112) comprising a voltage-controlled magnetic anisotropy (VCMA) region (118) serving as a controlled- barrier. A drive unit (114) applies charge current to generate driving torque for skyrmionium propagation. The controlled-barrier prevents transmission of an individual skyrmionium and facilitates transmission of at least one skyrmionium through majority-input interaction. An output nanotrack (116) conveys the transmitted skyrmionium, wherein the skyrmionium’s presence and absence represent first and second output logic states, respectively. [Figure 1]
