✦ Synopsis

Effect of irradiation by fast neutrons on superconducting and normal state properties of the YBa_Cu_0_ samples is presented Transport measurements showed a J7 degradation of all superconducting parameters, espeeially the transport critical current density.

Critical current densities obtained from magnetization data exhibited a substantial increase /about 15 times at 7~ K and H ~710 k0~/ after the irradiation with the fluence in the range 2.4-i0~ + 8.7.10 n/cm . Such an anomalous bahavior is explained in terms of neutron created defects at intergrain regions and improved intragrain pinning.

The photopyroelectric (PPE) technique has been used to study the effect of thermal cycling on normal state thermal properties of YBa2Cu307\_x thin films. For an optically opaque and thermally thin sample, the PPE voltage amplitude (V) is inversely proportional to the specific heat of the sample. Hys
