The demand for ever-increasing density of information storage and speed of
manipulation boosts an intense search for new magnetic materials and novel ways
of controlling the magnetic bit. Here, we report the synthesis of a ferromagnetic
photovoltaic CH(3)NH(3)(Mn:Pb)I(3) material in which the photo-excited electrons
rapidly melt the local magnetic order through the Ruderman-Kittel-Kasuya-Yosida
interactions without heating up the spin system. Our finding offers an
alternative, very simple and efficient way of optical spin control, and opens an
avenue for applications in low-power, light controlling magnetic devices.
