Journal ArticleDOI
Phase Transitions in the Gd 0.5 Ba 0.5 CoO 3 Perovskite
TL;DR: Magnetization measurements of a perovskitel-like compound have revealed an anomalous behavior at the temperature range between T i and T c i, which corresponds to appearing and disappearing spontaneous magnetization as discussed by the authors.
Journal ArticleDOI
Magnetocaloric effect in La1−xSrxMnO3 for x=0.13 and 0.16
A. Szewczyk,H. Szymczak,Andrzej Wiśniewski,K. Piotrowski,R. Kartaszynski,Bogdan Dabrowski,S. Koleśnik,Z. Bukowski +7 more
TL;DR: In this paper, the authors measured the magnetic contribution to entropy under influence of the magnetic field, allowing to estimate the value of magnetocaloric effect, and found that the changes reached ∼7 J/(kg) K in the field of 7 T.
Journal ArticleDOI
Magnetic and electrical properties ofLBaMn2O6−γ(L=Pr,Nd, Sm, Eu, Gd, Tb) manganites
TL;DR: In this paper, the influence of cation order-disorder phenomena on the crystal structure, magnetic and electrical transport properties of new CMR perovskites for LBaMn 2 O 6 - γ (L=Pr, Nd, Sm, Eu, Gd, Tb) series has been investigated.
Journal ArticleDOI
Magnetic state of the structural separated anion-deficient La 0.70 Sr 0.30 MnO 2.85 manganite
TL;DR: In this article, the results of neutron diffraction studies of the La0.70Sr0.30MnO2.85 compound and its behavior in an external magnetic field are stated.
Journal ArticleDOI
Critical behavior of La0.825Sr0.175MnO2.912 anion-deficient manganite in the magnetic phase transition region
TL;DR: In this article, the specific magnetization, the dynamic magnetic susceptibility, and the heat capacity of anion-deficient manganite were investigated, and it was shown that the ferromagnetic matrix of the material under study is characterized by a scatter in the exchange interaction intensities.
