Abstract Manganese oxides (R, A) MnO 3 (R= La, Y, Bi or rare earth metal, A= non-trivalent
doping element) have been one focus of research for two outstanding properties:(i) …

The magnetocaloric effect describes the change in temperature of a magnetic material under
adiabatic conditions through the application or removal of an external magnetic field. This …

We review lattice, thermodynamic, transport, high-frequency, and optical properties of Re 1−
x D x MnO 3 manganites, where Re is a rare earth and D is usually an alkaline-earth …

We report the effect of progressive reduction of the annealing temperature on the
magnetocaloric effect MCE of La2/3Ca1/3MnO3 nanoparticles synthesized by the sol–gel …

From data of initial magnetization isotherms, the magnetic entropy change ΔS M of the
series of ferromagnetic perovskites La 2/3 (Ca 1− x Sr x) 1/3 MnO 3, with x= 0, 0.05, 0.15 …

This chapter attempts to systematically outline some fundamentals and key experimental
results concerning magnetic properties of perovskite manganites, focusing on (i) …

MnAs exhibits a first-order phase transition from a ferromagnetic, high-spin metal hexagonal
phase to a paramagnetic, lower-spin insulator orthorhombic phase at TC= 313 K. Here, we …

The paper deals with the dilatometric study of high-alloy martensitic tool steel with the
designation M398 (BÖHLER), which is produced by the powder metallurgy process. These …

The crystal and magnetic structure of manganite La 0.7 Sr 0.3 MnO 3 has been studied in
the pressure range 0–7.5 GPa and the temperature range 4–300 K. The ferromagnetic state …

The so-called Arrott plot, which consists in plotting H/M against M 2, with H the applied
magnetic field and M the magnetization, is used to extract valuable information in second …
