Latest Patents

Chopdekar’s patent, “Method of controlling the states and vortex chirality in hexagonal ring structures comprising nanoscale magnetic elements,” describes a way to produce specific magnetic states and vortex chiralities in artificial kagome spin ice. The method uses hexagonal rings of ferromagnetic islands, with selected narrower islands designed to have higher switching fields. Their placement influences the magnetic states formed during magnetization reversal and the chirality of vortices in the rings.

His patent, “Method of studying chirality controlled artificial kagome spin ice building blocks,” presents a fabrication approach for studying low-energy states in chirality-controlled kagome spin ice structures. It describes preparing a silicon substrate with polymethyl methacrylate resist, using electron-beam lithography, and positioning ferromagnetic islands along a honeycomb lattice in a determined magnetization direction.
