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 ...

Microestructura y comportamiento termomagnético de aleaciones (FeCo) (NbZr) (GeB) obtenidas por molienda
(2009)
Las propiedades de las aleaciones metálicas dependen de la microestructura y, en particular, de su tamaño de grano. Más aún, al reducirse este tamaño hasta longitudes del orden del nanómetro (materiales nanoestructurados), ...

Analysis of nanocrystallization kinetics and crystal size distribution under limited growth approach
(Elsevier, 2012)
Two different simulation approaches have been used to describe nanocrystallization processes: a limited growth approach, which is an extension from instantaneous growth approximation, and an average soft impingement ...

Combined kinetic and Bean–Rodbell approach for describing field-induced transitions in LaFe11.6Si1.4 alloys
(Institute of Physics Publishing, 2021)
We propose a combination of the Kolmogorov–Johnson–Mehl–Avrami nucleation and growth theory and the Bean–Rodbell model to describe the field-induced transition in LaFe11.6Si1.4 alloys. The approach is applied to a set of ...
