Abstract
Polycrystalline samples of Ho2Pt2In were studied by means of low-temperature electrical resistivity, π(π ), heat
capacity, πΆπ(π ), magnetic susceptibility, π(π ), and magnetization, π(π») measurements. The compound was
found to undergo a paramagnetic to ferromagnetic phase transition at ππΆ = 18 K and another phase transition
at π1 = 8.3 K, likely a magnetic structure reconstruction into an antiferromagnetic-like state. Furthermore,
magnetocaloric effect (MCE) in Ho2Pt2In was investigated via comprehensive inspection of magnetization
isotherms collected near the magnetic phase transitions. The results revealed the second-order character of
the transitions at ππΆ and π1. The compound was found to exhibit the MCE characteristics fairly similar to
those of typical magnetic refrigerant materials.
