Recent progresses in high T_c superconducting quantum interference device(SQUID)magnetometers are discussed.First, intrinsic sensitivity of the SQUID at T=77K is discussed.For this purpose, transport and noise properties of the bicrystal junction are clarified, and optimization of junction parameters is shown.We also discuss the quality of the SQUID from a comprehensive comparison between experiment and simulation of the SQUID characteristics.Next, we discuss issues to guarantee correct operation of the SQUID magnetometer in noisy environment, such as a method to avoid flux trapping due to earth magnetic field, high-bandwidth electronics and gradiometer.Finally, we briefly describe application fields of the high T_c magnetometer.
