	1	Effects of irradiation on superconducting properties of small-grained MgB_(2) thin films显示文摘We investigate the effect of ion irradiation on MgB_(2) thin films with small grains of approximately 122 nm and 140 nm.The flux pinning by grain boundaries is insignificant in the pristine MgB_(2) films due to good inter-grain connectivity,but is significantly improved after 120-keV Mn-ion irradiation.The scaling behavior of the flux pinning force density for the ion-irradiated MgB_(2) thin films with nanoscale grains demonstrates the predominance of pinning by grain boundaries,in contrast to the single-crystalline MgB_(2) films where normal point pinning was dominant after low-energy ion irradiation.These results suggest that irradiation-induced defects can accumulate near the grain boundaries in metallic MgB_(2) superconductors.	刘丽 Jung Min Lee Yoonseok Han Jaegu Song Chorong Kim Jaekwon Suk Won Nam Kang 刘杰 Soon-Gil Jung Tuson Park	2023	Chinese Physics B2023，32，12：	0
