Formation and stability of icosahedral phase in Al65Ga5Pd17Mn13 alloy
T. P. Yadav, M. A. Shaz, R. S. Tiwari +1
In this work, we present the formation and characterization of a quaternary (pseudo ternary) icosahedral quasicrystal in Al65Ga5Pd17Mn13 alloy. The X ray diffraction and transmissi…
Synthesis of nanocrystalline Spinel phase by Mechanical Milling of Al-Cu-Fe and Al-Cu-Cr-Fe Quasicrystalline alloys
T. P. Yadav, N. K. Mukhopadhyay, R. S. Tiwari +1
In the present study, low-temperature synthesis of (Cu Fe)Al2O4 and (Cu Cr Fe)Al2O4 spinels from the quasicrystalline phases was investigated with the variation of process paramete…
Synthesis of nanocrystalline (Co,Ni)Al2O4 spinel powder by mechanical milling of quasicrystalline material
T. P. Yadav, N. K. Mukhopadhyay, R. S. Tiwari +1
The (Co,Ni)Al2O4 is an aluminum transition metals oxide which falls into the category of aluminate spinels. The synthesis of nano-crystalline spinels has been investigated extensiv…
Study on the Formation of Nano tau 3 Phase by Mechanical Alloying
T. P. Yadav, N. K. Mukhopadhyay, R. S. Tiwari +1
In the present investigation the pure elemental powder mixture of Al (70 at%) Ni (15 at %), Cu (15 at %) was mechanically milled in an attritor ball mill for 10, 20, 40, 60, 80 and…
Effect of La Doping on Microstructure and Critical Current Density of MgB2
Chandra Shekhar, Rajiv Giri, R S Tiwari +3
In the present study, La-doped MgB_2 superconductors with different doping level (Mg1-xLaxB2; x=0.00, 0.01, 0.03 & 0.05) have been synthesized by solid-state reaction route at ambi…
Colossal Magnetoresistance Study in Nanophasic La_0.7Ca_0.3MnO_3 Manganite
U. K. Goutam, P. K. Siwach, H. K. Singh +2
In this study we report the effect of sintering temperature on the low field magnetotransport properties of La_0.7Ca_0.3Mn_O3 manganite synthesized through polymeric precursor rout…
