Nb-doping in (Mn,Fe)2(P,Ge) giant magnetocaloric materials

APL Materials
The influence of Nb substitutions on the structure, magnetoelastic transition, and magnetocaloric properties is investigated in MnFe1−xNbxP0.76Ge0.24 (x = 0, 0.02, 0.04, 0.6) compounds. Powder XRD show that the compounds crystallize in the hexagonal Fe2P-

A quantitative criterion for determining the order of magnetic phase transitions using the magnetocaloric effect

Nature Communications, 2018
The ideal magnetocaloric material would lay at the borderline of a first-order and a second-order phase transition. Hence, it is crucial to unambiguously determine the order of phase transitions for both applied magnetocaloric research as well as the ...

Direct Observation of Microstructure Effect on Martensitic Transformation in Multifunctional Ni–Co–Mn–Ti Alloy

Small Structures, Volume 7, Issue 1, January 2026.
Microstructure engineering is utilized to control martensitic transformation of all‐d‐metal alloys and is directly observed via in situ Lorentz transmission electron microscopy. The appearance of magnetic vortexes and its evolution not only highlight a new potential application scenario for Ni–Co–Mn–Ti alloy in magnetic storage but also reveal the ...

Influence of Layering and Curie Temperature Uncertainty on the Performance of Multilayer Active Magnetic Regenerators

Advanced Functional Materials, Volume 35, Issue 52, December 23, 2025.
This study examines how manufacturing uncertainties in Curie temperatures (1.5–2°C) affect multilayer active magnetic regenerators (AMR). While increasing the number of magnetocaloric layers boosts cooling power, performance degrades due to temperature variations.
