WebNel caso in cui la giunzione del contatto Schottky sia abbastanza netta, un elevato gradiente di campo elettrico si instaura intorno ad esso limitando la tensione inversa di breakdown. A 90o pulse applied in conjunction with a magnetic field gradient will rotate spins which are located in a slice or plane through the object.
