One class of devices whose final measured output is this quantity can have “herringbone” or “barber pole” geometries, which (15[1])contrast with the multilayer CIP and CPP configurations. To improve sensitivity, optically pumped devices for measuring this quantity may use a very dense gas (-5[1])of alkali metal atoms to prevent decoherence, thus operating in the SERF regime. (15[1])Another device whose final measured (-5[1])output is this quantity comes in (*) RF and (15[1])DC types, the latter of which consists of a superconducting loop (15[1])with two Josephson (10[1])junctions in parallel. (10[1])SQUIDs measure this (10[1])quantity, (-5[2])external values of which produce a (-5[1])transverse (10[1])voltage in a Hall effect (10[1]-5[1])sensor. Inductive sensors detect the current produced (10[1])in a (-5[1])coil to measure, (10[1])for 10 points, what quantity, whose (10[1])SI unit is the Tesla? (10[1])■END■ (10[2])
