AB - R<inf>5</inf>Pd<inf>2</inf> compounds are known to exhibit magnetic glass transition and large cooling power in the cryogenic temperature region. All the R<inf>5</inf>Pd<inf>2</inf> (R = Ho, Dy, Dy<inf>0.6</inf>Gd<inf>0.4</inf>) compounds crystallize in the cubic Dy<inf>5</inf>Pd<inf>2</inf>-type of structure (space group Fd3m). The compounds Ho<inf>5</inf>Pd<inf>2</inf>, Dy<inf>5</inf>Pd<inf>2</inf>, and (Dy<inf>0.6</inf>Gd<inf>0.4</inf>)<inf>5</inf>Pd<inf>2</inf> undergo a paramagnetic to glass transition at 27 K, 38 K, and 58.5 K with a small hump at 10 K, 14 K, and 20 K respectively, confirming the double glass transitions present in these compounds. The maximum isothermal magnetic entropy changes (− ΔS<inf>max</inf>) for the compounds Ho<inf>5</inf>Pd<inf>2</inf>, Dy<inf>5</inf>Pd<inf>2</inf>, and (Dy<inf>0.6</inf>Gd<inf>0.4</inf>)<inf>5</inf>Pd<inf>2</inf> are 19.95 J/kg-K, 7.89 J/kg-K, and 7.4 J/kg-K with RCP values 987 J/kg, 549 J/kg, and 673 J/kg respectively for magnetic field change of 70 kOe. However, there is a controversy regarding the order of magnetic phase transition present in these compounds. A detailed investigation on the order of magnetic phase transition in Ho<inf>5</inf>Pd<inf>2</inf>, Dy<inf>5</inf>Pd<inf>2</inf>, and (Dy<inf>0.6</inf>Gd<inf>0.4</inf>)<inf>5</inf>Pd<inf>2</inf> compounds has been studied. Heat capacity measurements give a fingerprint of the absence of first-order magnetic phase transitions in these compounds. Field dependent magnetic entropy change studies on these compounds confirm the second-order nature of magnetic phase
