The correlation between static magnetoelectric coupling and magnetic structure was investigated in $TbMn_{0.98}Fe_{0.02}O_{3}$ with magnetic field up to 8 T and down to 2 K. Single-crystal neutron diffraction experiments reveal a substantial increase

We report a comprehensive study of the low-level substitution of Mn$^{3+}$ by Fe$^{3+}$ effect on the static and dynamic magnetoelectric coupling in TbMn$_{1-x}$Fe$_x$O$_3$ ($x=0$, 0.02 and 0.04). The cationic substitution has a large impact on the b

Magnetic properties of La0.8K0.2MnO3have been studied on nanoparticles prepared by glycine – nitrate method. As prepared nanoparticles and samples annealed at 300°C/2 hours adopt orthorhombic crystal structure (space group Pbnm). Crystal structure

We report electron tunneling spectroscopy studies on single crystalline FeSi sample performed for the case of homogeneous tunnel junction contacts and for the case of counter electrodes made from Pt-Rh alloy. Our results reveal that while the tunneli

Magnetization, AC susceptibility and specific heat measurements were performed on polycrystalline NdMn1-xFexO3+δ compounds (x = 0.0, 0.1 and 0.2). Substitution of Fe for Mn reduces the Néel temperature TN, which is associated with magnetic ordering

Exchange bias (EB) phenomena were first observed in the La1-xAgxMnO3 as prepared and heat treated (300 °C/2 hours) nanopowders (x = 0.10, 0.15 and 0.20) which were synthetized by self-combustion glycine-nitrate method. These nanoparticles have an av

In our paper we report on magnetic properties of La0.90Ag0.10(CoxMn1-x)O3 ferromagnetic ceramics (x = 0.00 and0.03) which were studied in pressures up to 0.9 GPa. Magnetic transition at the Curie temperature TC is accompanied with metal insulator tra
