"few atoms thick magnets enable smaller, more powerful devices, but at extremely cold temperatures, overcome by combining with topological insulator allowing electrons' smooth flow along its surface... magnetism stronger/ more stable when the 2 layered together, even at higher temperatures of that of liquid nitrogen's 77°K... stronger, more stable nanoscale magnets... future: room-temperature operation"
