Nanostructuring as a procedure to control the field dependence of the magnetocaloric effect
(Elsevier, 2017-01)
In this work, the field dependence of the magnetocaloric effect of Gd bulk samples has been enhanced through nanostructuring of the material. Nanostructuring consists in multilayers preparation by alternative rf-sputter ...

Correction of the Shape Effect on Magnetic Entropy Change in Ball Milled Fe70Zr30 Alloys
(Elsevier, 2018)
The field dependence of the magnetic entropy change (ΔSM) after mechanical alloying of Fe70Zr30 composition starting from high purity powders is studied. Samples with different shapes and different crystalline fraction X ...

First-order Phase Transition in High-performance La(Fe,Mn,Si)13H Despite Negligible Hysteresis
(Elsevier, 2023)
Optimizing the performance of magnetocaloric materials is facilitated by understanding the thermomagnetic transitions they undergo, including the order of these transitions and their strength. Those exhibiting strong ...

Grinding and particle size selection as a procedure to enhance the magnetocaloric response of La( Fe, Si)(13) bulk samples
(Elsevier, 2017-05)
The magnetocaloric effect of La(Fe,Si)13 samples deteriorates with the presence of secondary phases. However, it is highly challenging to produce single phase samples by conventional procedures and purification requires ...

Ball milling as a way to produce magnetic and magnetocaloric materials: a review
(Springer Nature, 2017)
Ball milling (BM) is a well-established technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (e.g., definition of an ...

Milling effects on the distribution of Curie temperatures and magnetic properties of Ni-doped La0·7Ca0·3MnO3 compounds
(Elsevier, 2020)
A systematic study of the magnetic and magnetocaloric properties around the ferromagnetic-paramagnetic phase transition temperature have been carried out on La0.7Ca0.3Mn1-xNixO3 (x = 0, 0.02, 0.07, 0.10) compounds ...
