Progressos recentes em alta Tc magnetômetros de dispositivos de interferência quântica supercondutores (SQUID) são discutidos. Primeiro, a sensibilidade intrínseca do SQUID em T=77 K é discutido. Para este propósito, as propriedades de transporte e ruído da junção bicristalina são esclarecidas e a otimização dos parâmetros da junção é mostrada. Também discutimos a qualidade do SQUID a partir de uma comparação abrangente entre experimento e simulação das características do SQUID. A seguir, discutimos questões para garantir o correto funcionamento do magnetômetro SQUID em ambientes ruidosos, como um método para evitar o aprisionamento de fluxo devido ao campo magnético terrestre, eletrônica de alta largura de banda e gradiômetro. Finalmente, descrevemos brevemente os campos de aplicação do alto Tc magnetômetro.

Abstract: Recent progresses in high Tc superconducting quantum interference device (SQUID) magnetometers are discussed. First, intrinsic sensitivity of the SQUID at T=77 K 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 Tc magnetometer.
