Wide dynamic range magnetic field cycler: Harnessing quantum control at low and high fields
A. Ajoy, X. Lv, E. Druga +11
We describe the construction of a fast field cycling device capable of sweeping a 4-order-of-magnitude range of magnetic fields, from ~1mT to 7T, in under 700ms. Central to this sy…
