Amplitude-dependent internal friction (ADIF) was measured in a polycrystalline niobium using four modes of flexural vibration from the fundamental to the third-order resonance at room temperature. The ADIF was detected in each vibration mode. The internal-friction versus strainamplitude curve of the
## Abstract Measurements are reported of the dependence of the upper critical field __H__~c 2~ on the concentration and configuration of Frenkel defects in niobium. The defects were produced by lowβtemperature irradiation with 3 MeV electrons and subsequent annealing treatments. The results qualita
