TL;DR: This work creates giant and reversible extrinsic magnetocaloric effects in epitaxial films of the ferromagnetic manganite La( 0.7)Ca(0.3)MnO(3) using strain-mediated feedback from BaTiO( 3) substrates near a first-order structural phase transition.

TL;DR: The magnetic, resonance, and electric properties of LaxMnO3+δ (0.815≤x≤1.0) polycrystalline samples have been studied in the temperature range of 77-370 K and at high pressures of up to 11.5 kbar.

TL;DR: In this article, the effect of an externally applied reversing magnetic field on the width of the thermomagnetic transition is studied experimentally and explained theoretically as a result of the interplay between the proximity-induced exchange and the Zeeman effects in the system.

TL;DR: In this article, the properties of ZnFe 2 O 4 nanoparticles synthesized by precipitation from non-aqueous solutions have been studied in transmission electron microscopy studies, and the specific loss power which is released on the exposure of an ensemble of synthesized particles to an electromagnetic field is calculated and measured experimentally.

TL;DR: This paper analyzes mechanisms of AC losses in a fluid based on magnetic nanoparticles, with special emphasis on the domains of their validity, and shows that the mechanisms may become qualitatively different as experimental conditions change from magnetostatic to high-frequency ones.
