Local structure around Mn and Co in LaMn(1-x)Co(x)O(3) +/-delta: An EXAFS study

Palikundwar, U.A.; Sapre, V.B.; Moharil, S.V.; Priolkar, K.R. (Journal of Physics-Condensed Matter. 21(23); 2009; Article ID: 235405.)

Detailed investigations of extended x-ray absorption fine structure (EXAFS) associated with the K-edges of Mn and Co have been carried out for LaMn(1-x)Co(x)O(3) +/-delta (0.3 less than or equal to x less than or equal to ...
On the use of a silicon crystal in a cauchois-type bent crystal x-ray spectrograph

Deshpande, S.D.; Moghe, N.V.; Sapre, V.B.; Mande, C. (Measurement Science and Technology. 1(11); 1990; 1250-1253.)

The authors have studied the copper K absorption discontinuity in the metal and its oxides using a Cauchois-type bent crystal x-ray spectrograph equipped with a silicon crystal, along with a conventional x-ray source. The ...
Study of the electronic-structure of Yba2Cu3O7 by x-ray absorption-spectroscopy

Deshpande, S.D.; Moghe, N.V.; Vishnoi, A.D.; Sapre, V.B.; Mande, C. (Physica Status Solidi A- Applications and Materials Science. 124(2); 1991; K133-K136.)
Study of the environment of copper in some ternary chalcogenide by EXAFS spectroscopy

Deshpande, A.P.; Sapre, V.B.; Mande, C. (Physica Status Solidi B-Basic Research. 145(1); 1988; 77-88.)

The EXAFS data of the K absorption discontinuity of copper in some ternary chalcogenides obtained earlier are reanalysed using the graphical method originally proposed by Lytle, Sayers, and Stern. It is shown that the ...
A study of the white lines associated with the rare-earth lii and liii absorption discontinuities in some oxides and tungstates

Vishnoi, A.D.; Sapre, V.B.; Mande, C. (Physica Status Solidi B-Basic Research. 161(2); 1990; 891-896.)

The intensities are studied of the white lines associated with the L,, and LllI absorption discontinuities of the rare earth elements in their oxides RE sub(2)O sub(3) (RE = La, Ce, Pr, Nd, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb ...
Tungsten L-absorption spectra in some rare-earth tungstates

Vishnoi, A.D.; Sapre, V.B.; Mande, C. (Journal of Physics and Chemistry of Solids. 52(8); 1991; 921-925.)

The L absorption spectra of tungsten in the pure metal, in the oxide WO3 and some tungstates RE2(WO4)3 (where RE = La, Ce, Nd, Sm, Gd and Dy) have been studied employing a 0.4 m Cauchois type bent crystal spectrograph. The ...
XANES study of tungsten LIII discontinuity in some rare earth tungstates

Vishnoi, A.D.; Sapre, V.B.; Mande, C. (X-Ray Spectrometry. 17(6); 1988; 213-215.)

The shape and near edge structure of the L sub(III) absorption discontinuity of tungsten in some rare earth tungstates, RE sub(2)(WO sub4))sub(3), were studied using a 40 cm Cauchois-type transmission x-ray spectrograph. ...
