SmCo$_5$ and YCo$_5$ are isostructural compounds both showing large magnetocrystalline anisotropy, where the former originates mainly from the crystal-electric field and magnetic interactions. We investigate the contribution of both interactions by partially substituting Y by Sm in as-cast polycrystalline Y$_{1-x}$Sm$_{x}$Co$_5$ (with $x$=0.00, 0.12, 0.18, 0.31, and 0.40) and measuring their structural, magnetic, and electrical properties through X-ray diffraction, magnetization, and electrical transport measurements. Our results suggest an interplay between microstructure strain in as-cast samples and the electronic and magnetic interactions.

Author comments upon resubmission

We thank the referee for his/her work revising our manuscript, where he/she judges our manuscript deserves a publication in the conference proceedings after minor corrections. We performed EDS measurements on our samples to determine the stoichiometries with the respective error bars. We we are resubmitting our manuscript including all the corrections the referee pointed out.

List of changes

1) We included in the text and Table 1 the standard deviation in the Sm composition according to SEM and EDS analysis.

2) We included the data for x=0.12 and x=0.4 in Figure 6.
