Unusual suppression of superconductivity in YNi2B2C under neutron irradiation

The behavior of electrical resistivity rho(T), temperature of superconducting transition Tc, and upper critical field Hc2(T) of polycrystalline YNi2B2C after irradiation with thermal neutron and subsequent high-temperature isochronous annealings in the temperature range Tann = 100 - 1000C has been studied.
