Effect of oxygen content on the magnetic and transport properties of Pr0.5Ba0.5MnO3-γ
TL;DR: In this paper, it was shown that oxidized La0.5Sr0.75 and reduced Pr 0.5Ba 0.75 samples exhibit similar magnetic and magnetoresistive properties.
Antiferromagnet-ferromagnet and structural phase transitions in La 0.88 MnO x manganites
TL;DR: In this paper, the crystal and magnetic properties of manganites have been investigated as a function of oxygen content by x-ray, neutron diffraction, Young's modulus, magnetization, and resistivity measurements.
Magnetostriction in thin films of manganites and cobaltites
Bohdan Kundys,H. Szymczak +1 more
TL;DR: In this paper, a comparison of the magnetostriction effects in manganite and cobaltite thin films has been presented, and it has been shown that magnetoelastic stress was measured using capacitance cantilever technique in wide temperature range 4.2-300 K.
Ferromagnetic state of La 1 − x Ba x CoO 3 under applied pressure: Factors controlling the sign reversal of pressure effect in cobaltites
I. M. Fita,I. M. Fita,R. Szymczak,Roman Puzniak,A. Wisniewski,I. O. Troyanchuk,Dmitry V. Karpinsky,V. Markovich,H. Szymczak +8 more
TL;DR: In this paper, the effect of applied pressure on magnetic properties of polycrystalline cobaltites was studied by magnetization measurements in the temperature range 5-240 K, magnetic field up to 16 kOe, and under hydrostatic pressure up to 10.5 kbar.
