Abstract
A new dc Josephson Inductive Kinetic Amplifier (IKA) has been proposed to measure weak magnetic fields with high sensitivity. In the present work the quantum noise intrinsic to the device is analyzed at 4.2K an d we show that the IKA is capable of subquantum limit measurement of d c magnetic fields.
