Tuning the Reversible Magnetocaloric Effect in Ni–Mn–In‐Based Alloys through Co and Cu Co‐Doping

Advanced Electronic Materials, 2019
The reversibility of the giant magnetocaloric effect (MCE) through the magnetic field–induced magnetostructural transformation in Ni–Mn–In‐based alloys is a key issue towards the potential magnetic refrigeration applications.

Engineering molecular rings for magnetocaloric effect

Applied Physics Letters, 2004
By substituting one Cr3+(s=3/2) with Cd2+(s=0) in molecular octanuclear rings, a diluted ensemble of identical nanomagnets with a S=3/2 ground state, weakly split in zero field, is obtained. The lattice contribution and the essential parameters of the spin Hamiltonian of these uncompensated antiferromagnetic cyclic spin systems are determined by ...

Simple enhancement of the magnetocaloric effect in giant magnetocaloric materials

Applied Physics Letters, 2003
A simple method of enhancing the magnetocaloric effect (MCE)) in ferromagnetic materials is described. Thin layers of pure Fe of 0.1- and 0.2-μm thickness were evaporated onto both sides of polished 0.6-mm, slices of the giant magnetocaloric material Gd5Si1.5Ge2.5.

Magnetocaloric Effect and Materials

2009
A brief review for magnetocaloric effect (MCE), including its potential application to magnetic refrigeration and the corresponding magnetic materials, has been given. Focuses are recent progresses in the exploration of magnetocaloric materials which exhibit a first-order phase transition, thus a giant MCE.

Magnetocaloric effect in La1.25Sr0.75MnCoO6

Journal of Thermal Analysis and Calorimetry, 2013
The magnetocaloric properties of La1.25Sr0.75MnCoO6 (LSCM) manganites that were synthesized at 750 and 1,300 °C have been investigated. It is found that magnetic entropy change distribution of the LSCM is much more uniform than that of gadolinium. This feature is desirable for an Ericson-cycle magnetic refrigerator.

A series of [2 × 2] square grid LnIII4 clusters: a large magnetocaloric effect and single-molecule-magnet behavior

New Journal of Chemistry, 2019
Four new [2 × 2] square grid LnIII4 clusters were successfully synthesized by employing a multidentate chelating Schiff base ligand. Magnetic studies showed that cluster 1 displays a larger magnetocaloric effect (−ΔSm = 34.46 J kg−1 K−1 for ΔH = 7.0 T at

Magnetocaloric effect in ferrite nanoparticles

Journal of Magnetism and Magnetic Materials, 2006
Abstract A comparative study of the magnetocaloric effect (MCE) is reported in two different types of chemically synthesized magnetic nanoparticle systems—cobalt ferrite and manganese zinc ferrite with mean size around 5 and 15 nm, respectively.

Magnetocaloric Effect in ErSi Compound

IEEE Transactions on Magnetics, 2011
The magnetic properties and magnetocaloric effects (MCEs) have been investigated in ErSi compound, which crystallizes in the orthorhombic CrB-type structure. This compound is antiferromagnetic (AFM) with a Neel temperature TN of 12.5 K. The measurements of the temperature and field dependences of the magnetization clearly show that the ErSi compound ...
