Summary: | A novel device — a magnetic field controlled microwave microstrip resonator based on high-Tc superconducting material — has been realised in which the quality factor Q is strongly influenced by a small external magnetic field. The field changes the SQUID phenomena in the film. Increasing the field first causes the Q value to reach a maximum but further increasing the field decreases amount of the pairs and there is a decrease in Q below the zero field value. Other kinds of microwave devices can also be constructed employing this technique. |
