Superconductivity at 12 K in Y-Ni-B system
Abstract Sharp drop in resistivity and diamagnetic susceptibility below 12 K clearly indicate a superconducting (SC) transition in the system Y-Ni-B (nominal composition: YNi4B). Possibility of aExpand
Investigations of the structural, magnetic and Ce-valence properties of quaternary CeM2B2C compounds (M=Co, Ni, Rh, Pd, Ir and Pt)
Polycrystalline samples with nominal formula CeM2B2C (M=Fe, Co, Ni, Cu, Ru, Rh, Pd, Os, Ir, Pt and Au) were prepared by arc melting. CeM2B2C essentially forms as a single phase with the LuNi2B2C-typeExpand
BULK SUPERCONDUCTIVITY AT AN ELEVATED TEMPERATURE (TC 12 K) IN A NICKEL CONTAINING ALLOY SYSTEM Y-NI-B-C
We report here our discovery of bulk superconductivity at rather high T c in samples having nominal compositions YNi 4 BO 0.2 (T c ≊12.5 K) and YNi 2 B 3 O 0.2 (T c ≊13.5 K). While YNi 4 BC 0.2 seemsExpand
Large magnetic cooling power involving frustrated antiferromagnetic spin-glass state in R 2 NiSi 3 (R =Gd ,Er )
The ternary intermetallic compounds ${\mathrm{Gd}}_{2}{\mathrm{NiSi}}_{3}$ and ${\mathrm{Er}}_{2}{\mathrm{NiSi}}_{3}$ are synthesized in chemically single phase, which are characterized using dcExpand
Magnetic frustration induced large magnetocaloric effect in the absence of long range magnetic order
TLDR
The magnetic ground state of this material found to be highly frustrated without any long range order or glassy feature as investigated through magnetic, heat capacity and neutron diffraction measurements. Expand
Difference in spin state and covalence between La1−xSrxCoO3 and La2−xSrxLi0.5Co0.5O4
We present a comparative study of the spin states and electronic properties of La1-xSrxCoO3 and La2-xSrxLi0.5Co0.5O4 using X-ray absorption near-edge structure spectroscopy at both the O-K andExpand
Valence electron distribution in La2Li1/2Cu1/2O4, Nd2Li1/2Ni1/2O4, and La2Li1/2Co1/2O4
Abstract The distribution of valence electrons between transition metals (TM) and oxygen has been studied via X-ray absorption near-edge fine structure (XANES) at the TM-L 2, 3 and O-K thresholds forExpand
Anomalous magnetoresistance in antiferromagnetic polycrystalline materials R2Ni3Si5 (R=rare earth)
Magnetoresistance (MR) studies on polycrystalline R2Ni3Si5, (R=Y, rare earth) which order antiferromagnetically at low temperatures, are reported here. MR of the Nd, Sm, and Tb members of the seriesExpand
Low-field induced large magnetocaloric effect in Tm2Ni0.93Si2.93: influence of short-range magnetic correlation.
TLDR
A new intermetallic compound Tm2 that forms in single phase only in defect crystal structure that exhibits a large magnetic entropy change and adiabatic temperature change and is considered to be responsible for such a large magnetocaloric effect over a wide temperature region. Expand
Magnetic phase inhomogeneity in frustrated intermetallic compound Sm2Ni0.87Si2.87
Abstract A new ternary compound Sm 2 Ni 0.87 Si 2.87 , belonging to intermetallic R 2 TX 3 family ( R  = rare-earth, T = transition metals, X = Si, Ge, etc. ), could be synthesized in single phaseExpand
