Producción y caracterización de películas delgadas de YBaCo4O7+δ por medio de pulverización catódica (sputtering) a presiones altas de oxígeno
Montoya Carvajal, Juan FernandoThe successful growth of thin films of the novel cobaltite YBaCo4O7+ δ by dc sputtering technique at high oxygen pressure onto r (1012) sapphire substrates is reported. The films were characterized after their structural, ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas. -
Role of the Al-doping and epitaxial strain in the multiferroic behavior of TbMnO3 bulk and thin films
Izquierdo Núñez, Jorge LuisThe Ph.D. thesis reports on the experimental investigation of the structure and physical properties of the perovskite-type multiferroic TbMnO3 when doped with aluminum ions in different atomic positions. The study is carried ...Universidad Nacional de Colombia Sede Medellín Facultad de Ciencias Escuela de Física.
