20.500.12556/RUL-183569 Direct observation of room-temperature electrocaloric and magnetocaloric responses in multicaloric composite films For the first time, room-temperature electrocaloric (EC) and magnetocaloric (MC) effects were observed in multicaloric composites using direct characterization methods. By combining the EC ceramic 0.9Pb(Mg▫$_{1/3}$▫Nb▫$_{2/3}$▫)O▫$_{3}$▫–0.1PbTiO▫$_{3}$▫ (PMN–10PT) with the MC La-Fe-Si-Co (LFSC) alloy, the multicaloric films were prepared. The PMN–10PT films exhibited a dielectric permittivity of ∼600, while composites exhibited improved values at ∼700. The room-temperature EC response of composites was ∼0.45 K at 250 kV cm▫$^{−1}$▫, a 32 % enhancement when compared to PMN–10PT films. This enhancement in composite films is attributed to Maxwell-Wagner-type polarization effects, induced by the embedded LFSC MC particles. The room-temperature MC response of composite films was directly characterized, achieving a MC response ∼1.4 K at 2 T, after corrections. Our results bring novel insights on the feasibility of preparing multicaloric composites with enhanced caloric properties for room-temperature micro-cooling technologies. multicaloric composites electrocaloric magnetocaloric multicaloric powder aerosol deposition thick films multikalorični kompoziti elektrokalorični odzivi magnetokalorični odzivi multikalorične plasti aerosolno nanašanje prahu debele plasti true false true Angleški jezik Slovenski jezik Članek v reviji 2026-06-15 12:30:02 2026-06-15 12:30:14 2026-06-16 04:04:30 0000-00-00 00:00:00 2026 0 0 9 str. issue 15, art. 118584 Vol. 46 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.5:620.168 0955-2219 10.1016/j.jeurceramsoc.2026.118584 281625091 Regis_..._Direct_observation....pdf Regis_..._Direct_observation....pdf 1 1F63381576A1E73967C046D39B56F3BE d3e05e69b90a30c5165d8d7f610e1e0e7d51f4811ef96e95a773569efe6d1ece 8287623f-68a6-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=235645 https://www.sciencedirect.com/science/article/pii/S0955221926004607 1 269f9790-68a5-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=235644 Fakulteta za strojništvo 0 0 0
