Designing a molecular magnetic button based on 4d and 5d transition-metal phthalocyanines

Abstract The field of molecular spintronics exploits the properties of organic molecules possessing a magnetic moment, either native in the form of radicals or induced by the insertion of transition metal magnetic ions. To realize logic or storage molecular spin-tronics devices, molecules with stabl...
