Gd1-xHoxNi melt-spun ribbons were fabricated by a single-roller melt spinning method. All the compounds crystallize in an orthorhombic CrB-type structure. The Curie temperature (T-C) was tuned between 46 and 99 K by varying the concentration of Gd and Ho. A spin reorientation (SRO) transition is observed around 13 K. Different from T-C, the SRO transition temperature is almost invariable for all compounds. Two peaks of magnetic entropy change (Delta S-M) were found. One at the higher temperature range was originated from the paramagnet-ferromagnet phase transition and the other at the lower temperature range was caused by the SRO transition. The maximum of Delta S-M around T-C is almost same. The other maximum of Delta S-M around SRO transition, however, had significantly positive relationship with x. It reached a maximum about 8.2 J kg(-1) K-1 for x = 0.8. Thus double large Delta S-M peaks were obtained in Gd1-xHoxNi melt-spun ribbons with the high Ho concentration. And the refrigerant capacity power reached a maximum of 622 J kg(-1) for x = 0.6. Gd1-xHoxNi ribbons could be good candidate for magnetic refrigerant working in the low temperature especially near the liquid nitrogen temperature range.
