A ^63,65Cu NMR study was carried out on a series of Cu_1–xPd_xFeS₂ compounds (x = 0–0.02) in a local magnetic field at 77 K. The spectra of the samples were taken. Their parameters were determined and the fields in the region of ^63,65Cu nuclei were estimated. Asymmetric broadening of the NMR resonance lines was found along with a smoother decay in the high-frequency region, which may result from an increase in the amount of defects in the crystal lattice of the compound. These can be FeCu²⁺ antistructural defects, whose formation is attributed to the generation of the PdS phase in the chalcopyrite matrix with an increase in the nominal Pd content.

甲^63,65的Cu NMR研究是对一系列的Cu进行_1-x的Pd _X的FeS _2种取化合物（X = 0-0.02）在局部磁场在77K的样品的光谱。确定了它们的参数并估计了^63,65 Cu核区域中的场。发现NMR共振线的不对称加宽以及高频区域的平滑衰减，这可能是由于化合物晶格中缺陷数量的增加所致。这些可能是FeCu ^2+的抗结构缺陷，其形成归因于黄铜矿基质中PdS相的产生以及标称Pd含量的增加。
