      abstract     = {Magnetocaloric refrigeration is one of the most promising
                      next-generation solid-state caloric techniques to
                      revolutionize the traditional air-compression technique. The
                      La(Fe,Si)$_{13}$-based materials are recognized as
                      candidates with potential for practical applications.
                      However, flexible strategies to improve the Curie
                      temperature (T$_C$) and further achieve the tunable giant
                      magnetocaloric effect (GMCE) still need to be developed.
                      Here, the systematic experimental investigation on a series
                      of light elements (C, F, S) modified LaFe$_{11.6}$Si$_{1.4}$
                      compounds are presented. It is found that all modified
                      samples exhibit a higher T$_C$, with a negligible impact on
                      the thermal hysteresis. The GMCE performance in C- and
                      S-modified samples is significantly degraded, but the
                      maximum magnetic entropy change |Δ s$_m$| for the optimally
                      doped F sample can be well maintained at 19.2 J kg$^{−1}$
                      K$^{−1}$ for a field change of 2 T. The preferential site
                      occupancy of dopants is determined, and the microstructural
                      observation and metastable atomic changes have also been
                      analyzed. It is concluded that interstitial doping is more
                      efficient to shift T$_C$. The first-order transition can
                      however not be maintained upon doping due to changes in the
                      hybridization. These findings highlight the importance of
                      the interplay between the lattice pressure effect and the
                      covalent hybridization for this material family.},
