Journal ArticleDOI
Magnetic nanoparticle-based hyperthermia for cancer treatment
TL;DR: Nanotechnology provides a novel and original solution with magnetic hyperthermia, which is based on the use of magnetic nanoparticles to remotely induce local heat when a radiofrequency magnetic field is applied, provoking a temperature increase in those tissues and organs where the tumoral cells are present.
Journal ArticleDOI
Structural details and magnetic order of La 1-x Sr x CoO 3 (x<=0.3)
Roberto Caciuffo,Daniele Rinaldi,Gianni Barucca,Jorge Mira,José Rivas,María Antonia Señarís-Rodríguez,Paolo G. Radaelli,Dino Fiorani,John B. Goodenough +8 more
TL;DR: In this paper, the authors studied the magnetic properties of perovskite and found that the holes introduced by Sr doping are attracted to the ions where they stabilize to lowest temperatures an intermediate-spin state at neighboring trivalent cobalt.
Journal ArticleDOI
Change from first- to second-order magnetic phase transition in La 2 / 3 ( C a , S r ) 1 / 3 MnO 3 perovskites
TL;DR: In this article, it was shown that not all the title perovskites exhibit a first-order transition at their Curie temperatures, while all the second-order ones do.
Journal ArticleDOI
Influence of Dipolar Interaction on Magnetic Properties of Ultrafine Ferromagnetic Particles
TL;DR: From the zero field cooling (ZFC)/field cooling (FC) simulations, the blocking temperature T(B) clearly increases with increasing strength of interaction, but it is almost not effected by a broadening of the distribution of particle sizes.
Journal ArticleDOI
Giant magnetoresistance in fine particle of La0.67Ca0.33MnO3 synthesized at low temperatures
Rodolfo Sánchez,José Rivas,Carlos Vázquez-Vázquez,§ and M. Arturo López-Quintela,M.T. Causa,M. Tovar,S. B. Oseroff +6 more
TL;DR: In this paper, a solgel method was used to obtain monodispersive particles of La0.67Ca0.33MnO3 in the range from 20 to 110 nm at temperatures from 540 to 1000 °C.
