✦ Synopsis

The microwave absorption in a weak magnetic field H << He(T) is reported in pure polycrystalline tin in the superconducting state near To. A novel experimental technique is used which employs an ESR apparatus with the perpendicular configuration of the static and microwave magnetic fields and the radio-frequency modulation of the static field. This measurement is related to the true superconducting state of the bulk material. The characteristic decrease of the microwave absorption in a static magnetic field is detected at 0.8 < T/TΒ’ < 0.98 and to/T~ = 0.12 which is predicted by the microscopic theory of the surface impedance of type-I superconductors.

The effect of temperature on low field dependent microwave absorption (LFDMA) in pure YBa2Cu3OT. ~ prepared by solid state reaction method is studied near To. Our results show that the peak position of LFDMA is slowly varying function of temperature near To. Peak height and hysteresis area of LFDMA
