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 ...

A unified approach to describe the thermal and magnetic hysteresis in Heusler alloys
(American Institute of Physics Publising LLC, 2016)
Different excitations, like temperature, magnetic field, or pressure, can drive a martensitic transition in Heusler alloys. Coupled phenomena in these materials lead to interesting magnetocaloric and barocaloric effects ...

Anisotropy field distribution in soft magnetic Hitperm alloys submitted to different field annealing processes
(Elsevier, 2016)
The magnetic anisotropy field distribution is discussed for Hitperm alloys annealed under different field conditions leading to different induced magnetic anisotropies: zero (ZF), transversal (TF), and longitudinal (LF) ...

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 ...

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 ...

Study of the Induced Anisotropy in Field Annealed Hitperm Alloys by Mössbauer Spectroscopy and Kerr Microscopy
(Springer Nature, 2016)
Samples of Fe39Co39Nb6B15Cu1 alloy were nanocrystallized under zero field annealing (ZF) and transverse field annealing (TF) conditions. A reduction in coercivity for TF samples with respect to ZF sample (16 and 45 A/m, ...

Applicability of scaling behavior and power laws in the analysis of the magnetocaloric effect in second-order phase transition materials
(American Physical Society, 2016)
In recent years, universal scaling has gained renewed attention in the study of magnetocaloric materials. It has been applied to a wide variety of pure elements and compounds, ranging from rare earth-based materials to ...
