摘要:

本文研究了快中子辐照引起的原子无序对多晶样品FeSe正常态和超导态性质的影响。在辐照温度Tirr ~ 50 \degree C时,用注量高达1.25 \cdot 10^20 cm^-2的快中子辐照,超导转变温度T_c和电阻率Rho_25的变化相对较小。这种行为被认为是可追溯到相当低的,相对于在给定的照射温度下可能的辐射缺陷浓度,这是由更简单的晶体结构引起的,考虑到其他层状化合物。

英文摘要:

Effect of atomic disordering induced by irradiation with fast neutrons on the properties of the normal and superconducting states of polycrystalline samples FeSe has been studied. The irradiation with fast neutrons of fluencies up to 1.25\cdot10^20 cm^-2 at the irradiation temperature Tirr ~ 50 \degree C results in relatively small changes in the temperature of the superconducting transition T_c and electrical resistivity Rho_25. Such a behavior is considered to be traceable to rather low, with respect to that possible at a given irradiation temperature, concentration of radiation defects, which is caused by a simpler crystal structure, considered to other layered compounds.
