Magnetic properties of Co x Pt 100−x nanoparticles

Journal of Science: Advanced Materials and Devices, 2016
Se prepararon nanopartículas de CoxPt100 −x (x = 50, 59 y 73) mediante la reducción química de cloruro de cobalto (II) y ácido cloroplatínico, luego se sometieron a ultrasonidos durante 2 h. Después del recocido a varias temperaturas de 450 °C a 700 °C durante 1 h, se observó un cambio de estructura y las muestras muestran propiedades magnéticas duras ...
