A New Method for Determining the Curie Temperature From Magnetocaloric Measurements
(Institute of Electrical and Electronics Engineers, 2016)
A new method is proposed for determining the Curie temperature from magnetocaloric measurements. It is based on the field dependence of the magnetic entropy change close to the Curie temperature. The main advantages over ...

Effect of α-Fe impurities on the field dependence of magnetocaloric response in LaFe11.5Si1.5
(Elsevier, 2015)
In this work, the theoretical field dependence of the magnetic entropy change far away from the transition is used to analyze the field dependence of composite materials formed by fcc La(Fe,Si)13 and bcc α-Fe(Si) phases. ...

Magnetocaloric response of amorphous and nanocrystalline Cr-containing Vitroperm-type alloys
(Elsevier, 2016)
The broad compositional range in which transition metal (TM) based amorphous alloys can be obtained, yields an easily tunable magnetocaloric effect (MCE) in a wide temperature range. In some TM-based alloys, anomalous ...

Analysis of magnetocaloric effect of ball milled amorphous alloys: Demagnetizing factor and Curie temperature distribution
(Elsevier, 2015)
The magnetocaloric effect (MCE) has been measured for an amorphous mechanically alloyed (MA) Co62Nb6Zr2B30. It is demonstrated that sample shape must be taken into account for a correct interpretation of the results, ...

Optimal temperature range for determining magnetocaloric magnitudes from heat capacity
(Institute of Physics Publishing, 2016)
The determination of the magnetocaloric magnitudes (specific magnetic entropy change, Δs M, and adiabatic temperature change, ΔT ad) from heat capacity (c H) measurements requires measurements performed at very low ...

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 ...

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 ...
