AI中文摘要：
采用EPR谱仪，对通过向临界温度为8 K的FeSe单晶进行氢热扩散得到的粉末状Fe-Se-H化合物，在3.6-25 K及295 K温度下，测量了高达6000 Oe磁场下的微波功率吸收与磁场的依赖关系。该依赖关系的形状及测量结果分析证实，Fe-Se-H化合物在常压下，于3.6-25 K及295 K（室温）均具有超导性。
英文摘要：
Using an EPR spectrometer, the dependences of microwave power absorption on magnetic field up to 6000 Oe were measured at temperatures of 3.6-25 K and 295 K in a powdered compound Fe-Se-H, obtained by thermal diffusion of hydrogen into a FeSe single crystal with a critical temperature of 8 K. The shape of the dependences and the analysis of the measurement results confirm the superconductivity of the Fe-Se-H compound at normal pressure, both at temperatures of 3.6-25 K and at 295 K, i.e., at room temperature.
