TL;DR: The crystal structure of Ni{sub 2+x}Mn{sub 1-x}Ga has been studied as a function of composition (x) by powder x-ray diffraction.
Journal ArticleDOI
Powder x-ray diffraction study of the thermoelastic martensitic transition in Ni 2 Mn 1.05 Ga 0.95
TL;DR: In this paper, the transformation behavior of these two alloys is found to be entirely different, and it is shown that the martensite phase belongs to the Pnnm space group with $7M$ modulation.
Journal ArticleDOI
Structural, magnetic, and transport properties of nanoparticles of the manganite Pr0.5Ca0.5MnO3
TL;DR: In this article, the structural, magnetic and transport properties of nanoparticles of Pr0.5Ca 0.5MnO3 (PCMO) were investigated with particle sizes as small as 15nm synthesized by polyol route.
Journal ArticleDOI
