Measuring the Curie temperature [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2013
AbstractCurie point temperatures (TC) of natural and synthetic magnetic materials are commonly determined in rock magnetism by several measurement methods that can be mutually incompatible and may lead to inconsistent results. Here the common evaluation routines for high‐temperature magnetization and magnetic initial susceptibility curves are analyzed ...

Curie temperature of multiphase nanostructures [PDF]

open access: yesJournal of Applied Physics, 2000
The Curie temperature and the local spontaneous magnetization of ferromagnetic nanocomposites are investigated. The macroscopic character of the critical fluctuations responsible for the onset of ferromagnetic order means that there is only one Curie temperature, independent of the number of magnetic phases present. The Curie temperature increases with

Critical temperature below the Curie temperature of ferroelectric ceramics PZT

open access: yesJournal of Advanced Dielectrics, 2021
The article presents the results of research the pre-transitional features of the behavior of solid solutions based on lead zirconate-titanate. The presence of a “special” critical temperature Td on the temperature dependences of the permittivity 𝜀(T ...

Magnetocaloric properties in (La,R)(Fe,Mn,Si)13H (R = Ce and Pr)—toward a better alloy design that results in a reduction in volume of permanent magnets and the establishment of long-term reliability in cooling systems

open access: yesJPhys Energy, 2023
The magnetocaloric effect (MCE) in La _1− _z R _z (Fe _0.89− _x Mn _x Si _0.11 ) _13 H _y _max (R = Ce and Pr) is verified in view of correlation between alloying recipes such as selection of doping elements and fundamental physics that governs MCE.

Piezoelectric ceramics with high piezoelectricity and broad temperature usage range

open access: yesJournal of Materiomics, 2021
There is a general observation that the Curie temperature and piezoelectric property of the ferroelectric ceramics can be enhanced only at the expense of each other, i.e., higher piezoelectricity, lower Curie temperature, thus, limits their applications ...
