Eu1 − xSrxAu4Cd2: a ferromagnetic solid solution with adjustable Curie temperature

Temperature-dependent magnetization in a ferromagnetic bilayer consisting of two materials with different Curie temperatures

A structure-dependent self-consistent mean-field model has been used to calculate the temperaturedependent magnetization in ferromagnetic bilayers that consist of two materials with different Curie temperatures. The magnetization versus temperature curves fSsTdg are found to be structure sensitive among the bilayer systems with simple cubic, face-centered-cubic, and body-centered-cubic structur...

Using ferromagnetic nanoparticles with low Curie temperature for magnetic resonance imaging-guided thermoablation

INTRODUCTION Magnetic nanoparticles (NPs) represent a tool for use in magnetic resonance imaging (MRI)-guided thermoablation of tumors using an external high-frequency (HF) magnetic field. To avoid local overheating, perovskite NPs with a lower Curie temperature (T c) were proposed for use in thermotherapy. However, deposited power decreases when approaching the Curie temperature and consequent...

Limits on the Curie temperature of „III,Mn...V ferromagnetic semiconductors

Mean-field-theory predicts that the Curie temperature Tc of a ~III,Mn!V ferromagnet will be proportional to the valence band density-of-states of its host ~III,V! semiconductor, suggesting a route toward room-temperature ferromagnetism in this materials class. In this letter, we use theoretical estimates of spin-wave energies and Monte Carlo simulations to demonstrate that long-wavelength colle...

Molecular tagging thermometry with adjustable temperature sensitivity

We report an extension to the technique of molecular tagging thermometry which allows for adjustable temperature sensitivity. The temperature dependence of laser-induced phosphorescence of the water-soluble phosphorescent triplex (1-BrNp MbCD ROH) is used to conduct temperature measurements in aqueous flows. It is shown that the temperature sensitivity of phosphorescence intensity can be adjust...
