Abstract

Polycrystalline samples of Ho₂Pt₂In were studied by means of low-temperature electrical resistivity, ρ(T), heat capacity, C_p(T), magnetic susceptibility, χ(T), and magnetization, M(H) measurements. The compound was found to undergo a paramagnetic to ferromagnetic phase transition at T_C = 18 K and another phase transition at T₁ = 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 T_C and T₁. The compound was found to exhibit the MCE characteristics fairly similar to those of typical magnetic refrigerant materials.
