We propose the use of a high-Tc Josephson junction array for the measurement of high-frequency magnetic fields with high spatial resolution. The voltage vs magnetic field (V-B) relationship of the bicrystal junction was studied for this purpose. The junction array fabricated with an area of 120 μm by 50 μm showed the conversion efficiency dV/dB = 63 V/T at T = 77 K. This value indicates that the junction array is more sensitive, up to 1.7 GHz, than the conventional induction coil having the same area. Measurement of the magnetic field with a frequency of 130 MHz was successfully demonstrated using the junction array. Performance of the junction array will be much improved by decreasing the operational temperature.
