Second-order magnetic phase transition in orthorhombic Pr0.7Ca0.15Ba0.15MnO3
TL;DR: In this paper, the critical behavior around the ferromagnetic-paramagnetic (FM-PM) phase transition (the Curie temperature, TC) of a polycrystalline manganite Pr0.7Ca 0.15Ba0.15MnO3.
Journal ArticleDOI
Structural Characterization and Magnetic and Electrical Properties of La0.7Ca0.3MnO3–La1.5Sr0.5NiO4 Nanocomposites
TL;DR: In this paper, a combination of the mechanical milling and solid-state reaction methods was used to synthesize (1 − x)La0.7Ca0.3MnO3 + xLa1.5Sr0.5NiO4 (x = 0 to 0.3) composites.
Journal ArticleDOI
Bottom IrMn-based spin valves by using oxygen surfactant
Jungseek Hwang,M. Y. Kim,Jang-Roh Rhee,Sang-Tae Lee,Do-Guwn Hwang,Jong Kyu Kim,Sanghyuk Lee,Seong-Cho Yu +7 more
TL;DR: In this paper, a bottom-Mn-based spin valve with the structure Ta30/NiFe20/IrMn70/CoFet/oxidation/CoFe(30−t)/Cu20/Co Fe30/Ta35 (all thickness in angstroms) was deposited by dc magnetron sputtering on thermally oxidized Si (111) substrates and the value of the magnetoresistance (MR) ratio was seen to be quite low at a relatively large t of >16 A and a exchange coupling field (Hex) decreases
Journal ArticleDOI
Micromagnetic Simulation of Damped Oscillatory Behavior of Domain Wall Propagation in Sinusoidal Ferromagnetic Nanowire
Hong-Guang Piao,Je-Ho Shim,Dede Djuhana,Sang-Hyuk Lee,Su-Hyeong Jun,C.-M. Heo,S. K. Oh,Seong-Cho Yu,Dong-Hyun Kim +8 more
TL;DR: In this article, the authors investigated a damped oscillatory behavior of domain wall propagation in wavy nanowires under an external field higher than the Walker breakdown field using micromagnetic simulation.
Journal ArticleDOI
Critical Behavior in La0.75Ca0.2Ag0.05MnO3 Exhibiting the Griffiths Phase
TL;DR: Investigation of the critical properties in the vicinity of the ferromagnetic (FM)–paramagnetic (PM) phase transition in a polycrystalline sample of La proves an existence of the Griffiths phase well above Curie temperature.
