BIZARRE ELECTRONIC SPIN
A group of international scientists led by physicists from Princeton University have filmed the strange behavior of electronic spin inside alloy of bismuth with antimony, which could lead to greater data storage capacity, improvements in electronics, more computing speed, better studies of quantum behavior, study of unusual behavior of magnets, superconductors and others, said Zahid Hasan, Princeton professor of physics (Science, Feb. 13).
In the experiment most electron returns to its normal position after giving 2 full turns (720 degrees), instead of the usual 360 degrees. In quantum domains a object can be in 2 places at the same time, also there is no distinction between waves and particles. Physicists agree that these bizarre circuits represent added alternatives to the usual and simple "on" and "off". The experiment has allowed the development of imaging techniques to follow quantum behavior. Now you can take photos of electronic spin, as they travel through the north and south poles of small intraelement magnets, hoping that this knowledge will improve medical images.

EXTRAÑA CONDUCTA DE SPIN ELECTRONICOS
Un grupo de científicos internacionales liderados por físicos de la Universidad de Princeton, han filmado la extraña conducta de spines electrónicos al interior de aleaciónes de bismuto con antimonio, que podrían conducir a una mayor capacidad de almacenamiento de datos, mejoras en la electrónica, mas velocidad de computación, estudios mejorados de conducta cuántica, conducta inusual de magnetos, superconductores y otros, dice Zahid Hasan profesor de fisica de Princeton (Science, Feb. 13).
En el experimento la mayoría de electrones retorna a su posición normal luego de dar 2 vueltas completas (720 grados), en véz de los 360 grados usuales. En dominios cuánticos un objeto puede estar en 2 lugares al mismo tiempo, no existiendo distinción entre ondas y partículas. Los físicos concuerdan en que estos circuitos bizarros, representan alternativas agregadas a los usuales y simples "on" y "off". El experimento ha permitido desarrollar además técnicas imagenológicas para objetivar la conducta cuántica. Ahora es posible tomar fotos del spin electrónico, mientras estos viajan por los polos norte y sur de pequeños magnetos intraelementos, esperándose que estos conocimientos mejoren la imagenología médica.
