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 ...

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 ...
