Giant Magnetostriction in Ferrimagnetic SmFe5As3

open access: yesAngewandte Chemie International Edition, EarlyView.
SmFe5As3 is a newly discovered ferrimagnetic material that displays peculiar volumetric effects as a function of temperature. As a result of two magnetic sublattices—one with d$d$‐electrons of Fe and another with f$f$‐electrons of Sm—single crystals of SmFe5As3 show negative (blue), positive (pink), and zero (beige) thermal expansion along the [010 ...

Direct measurements of the magnetocaloric effect in pulsed magnetic fields: The example of the Heusler alloy Ni$_{50}$Mn$_{35}$In$_{15}$

open access: yes, 2015
We have studied the magnetocaloric effect (MCE) in the shape-memory Heusler alloy Ni$_{50}$Mn$_{35}$In$_{15}$ by direct measurements in pulsed magnetic fields up to 6 and 20 T.

Influence of Carboxylate Ligand Variation on Structure, Magnetic Exchange, and Magnetocaloric Performance in Hexanuclear Gd(III) Complexes

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Hexanuclear cyclic Gd(III) coordination compounds are promising candidates for magnetic and magnetocaloric applications, yet systematic series remain rare due to synthetic challenges. We report the synthesis and characterization of five new complexes with the general formula [Gd(H3bt)(carboxylate)]6, employing four different carboxylate ...

Low computational cost semi-analytical magnetostatic model for magnetocaloric refrigeration systems

open access: yesAIP Advances, 2018
The analysis of the active magnetic refrigeration (AMR) cycle for different waveforms of both the magnetic field and the velocity of the heat transfer fluid is an essential challenge in designing and implementing heating and cooling systems based on the ...

Modeling the Maximum Magnetic Entropy Change of Doped Manganite Using a Grid Search-Based Extreme Learning Machine and Hybrid Gravitational Search-Based Support Vector Regression

open access: yesCrystals, 2020
The thermal response of a magnetic solid to an applied magnetic field constitutes magnetocaloric effect. The maximum magnetic entropy change (MMEC) is one of the quantitative parameters characterizing this effect, while the magnetic solids exhibiting ...

Magnetization process and magnetocaloric effect in geometrically frustrated Ising antiferromagnet and spin ice models on a `Star of David' nanocluster

open access: yes, 2017
Magnetic and magnetocaloric properties of geometrically frustrated antiferromagnetic Ising (IA) and ferromagnetic spin ice (SI) models on a nanocluster with a `Star of David' topology, including next-nearest-neighbor (NNN) interactions, are studied by an

Entropy‐Driven Innovations: Entropy Stabilized Oxides for High‐Performance Next‐Generation Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article explores high‐entropy‐stabilized oxides (HEOs) as novel functional materials for addressing critical issues in lithium–sulfur (Li–S) batteries, including lithium polysulfide (LPS) shuttling, inadequate conductivity, and slow redox kinetics.

New design of La(Fe, Co, Si)13 magnetocaloric composites using Gd as a binder

open access: yesJournal of Materials Research and Technology
We propose a new type of magnetocaloric composite that excludes the conventional use of non-magnetocaloric materials as the binder. Spark plasma sintering was adopted to make a fully dense La(Fe, Co, Si)13/Gd composite at low temperatures (450–600 °C ...

Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

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

open access: yesAPL 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-
