Abstract
Perfeccionamientos en magnetómetros de resonancia magnética nuclear, con acoplamiento de "spin", caracterizados porque comprenden dos muestra sometidas al campo que se trata de medir, que contienen los mismos núcleos atómicos de momento magnético y momento cinético no nulos; dos medias bobinas alineadas y asociadas cada tina a una muestra; medios para producir un campo electromagnético de frecuencia de resonancia electrónica suficiente para saturar una raya de una de las muestras que produce el aumento de la absorción de energía a la frecuencia de resonancia de los núcleos atómicos y una raya de la otra muestra que produce una emisión de energía a la citada frecuencia de resonancia de los núcleos atómicos; un amplificador diferencial, asociado a las dos medias bobinas, estando conectadas cada una de las medias bobinas a una tensión de referencia fija y a una entrada del amplificador, diferente para las dos medias bobinas, de modo que las tensiones parásitas inducidas en las medias bobinas aparecen en modo común, y estando conectada la salida del amplificador a las entradas por unas impedancias iguales y de valor elevado con respecto al de las medias bobinas; y medios de medida de la frecuencia a la salida del amplificador.
