new alloy sets magnetism benchmark

the burgeoning field of spintronics leverages electron spins—as opposed to their charge—to enhance solid-state devices like hard drives and cell phone components by prolonging battery life. spintronic developments, however, are increasingly running up against a barrier known as the slater-pauling limit, the maximum for how tightly a material can pack its magnetization. now, a new thin film is poised to break through this decades-old benchmark. a team of researchers from montana state university and lawrence berkeley national laboratory announces this week in applied physics letters, that they constructed a stable thin film made from iron, cobalt and manganese that boasts an average atomic moment potentially 50 percent greater than th...
