In this study, it is aimed to investigate the Krori-Barua type compact stars within the scope of f(R, L-m) theory. In this context, first, the field equations are obtained by considering the f(R, L-m) = R/2 + alpha L-m(n) model. Interestingly, the model offers chance to attain all components of matter without any restrictions. In addition, data sets from LMC X-4, EXO 1785-248 and Cen X-3 are used to analyze physical stability of the solutions. It is obtained that all conditions such as causality and stability. which indicate consistency between compact objects and f(R, L-m) theory are valid for the constructed model. We obtained that small values of n in the f(R, L-m) function show significant effect on the consistency of the star models. Therefore, different n values are considered for each star data set when graphing the physical states. Finally, necessary quantities of the model are defined, compared with the considered stars and discussed in detail.
