description: The work is devoted to measure the critical parameters (critical temperature and critical current) of the 2nd generation HTSC tape by non-contact magnetic methods and discussing the advantages of these methods compared to the traditional resistive method. The purpose of this work is to measure the critical current of an HTSC tape at liquid nitro-gen temperature using two non-contact methods: the method of measuring the magnetization and the method of trapped flux in the ring. The first method uses the measurement of the magnetization M with a sensitive vibrating magnetometer. The ribbon transition temperature Tc was determined from the dependences M(T), and from the dependences M(H) the width of the hysteresis loop in zero field was found and the critical current was found using the formulas.For the second method (using rings), the measurements were made according to a self-assembled scheme. A ring was cut out of the HTSC tape, a Hall sensor was installed in the center, the assembly with the ring and the sensor was placed in liquid nitrogen, a shielding current was induced in the ring using a strong permanent magnet, and when the magnet was removed, the magnetic flux was captured in the ring. From the magnetic field measured by the Hall sensor in the center of the ring, the critical current was calculated. The values of the critical current obtained by 2 different methods are matching in magni-tude with each other and the value given by the tape manufacturer. The data obtained indicates that the magnetic methods used make it possible to simply and reliably measure the critical current of an HTSC tape. These methods are free from the disadvantages of the resistive measurement method. The method of estimating the critical current from the trapped flux in the ring can be recommended to the tape manufacturer for calibrating their measuring setups.
