4f-hybridization effect on the magnetism of Nd2PdSi3, an anomalous magnetic compound
K. Mukherjee, Tathamay Basu, Kartik K. Iyer +1
Among the members of the series R2PdSi3 (R= Rare-earths), the magnetic behavior of the Nd compound is interesting in some respects. This compound is considered to order ferromagnet…
Contrasting magnetic behavior of fine particles of some Kondo Lattices
K. Mukherjee, Kartik K. Iyer, E. V. Sampathkumaran
We have investigated the magnetic behavior of ball-milled fine particles of well-known Kondo lattices, CeAu2Si2, CePd2Si2 and CeAl2, by magnetization and heat-capacity studies in o…
Isothermal magnetic entropy behavior in Tb5Si3: Sign reversal and non-monotonic variation with temperature, and implications
Niharika Mohapatraa, Sitikantha D. Das, K. Mukherjee +1
The magnetic entropy change (\DeltaS), a measure of the magnetocaloric effect, in Tb5Si3, a compound exhibiting unusual positive magnetoresistance following a magnetic-field-induce…
Evolution of a metastable phase with a magnetic phase coexistence phenomenon and its unusual sensitivity to magnetic field cycling in the alloys Tb5-xLuxSi3 (x <= 0.7)
K. Mukherjee, Kartik K. Iyer, E. V. Sampathkumaran
Recently, we reported an anomalous enhancement of the positive magnetoresistance beyond a critical magnetic field in Tb5Si3 in the magnetically ordered state, attributable to 'inve…
Magnetic behavior of bulk and fine particles of RCr2Si2C (R = La, Ce)compounds: possible magnetic ordering from Cr
K. Mukherjee, Kartik K. Iyer, E. V. Sampathkumaran
The magnetic behavior of the quaternary compounds, RCr2Si2C (R = La, Ce), has been investigated by magnetization (M) and heat-capacity (C) measurements (1.8-300 K) in the bulk poly…
A first-order magnetic phase transition near 15 K with novel magnetic-field-induced effects in Er5Si3
Niharika Mohapatra, K. Mukherjee, Kartik K. Iyer +1
We present magnetic characterization of a binary rare-earth intermetallic compound Er5Si3, crystallizing in Mn5Si3-type hexagonal structure, through magnetization, heat-capacity, e…
Glass-like ordering and spatial inhomogeneity of magnetic structure in Ba3FeRu2O9 : The role of Fe/Ru-site disorder
Srimanta Middey, Sugata Ray, K. Mukherjee +7
Several doped 6H hexagonal ruthenates, having the general formula Ba3MRu2O9, have been studied over a significant period of time in order to understand the unusual magnetism of rut…
Enhanced electrical resistance at the field-induced magnetic transitions in some stoichiometric and nonstoichiometric Tb-based ternary germanides
K. Mukherjee, Kartik K Iyer, E. V. Sampathkumaran
We present the magnetic and transport behavior of some Tb compounds, viz., TbIrGe2, TbFe(0.4)Ge2, and TbCo(0.4)Ge2. The stoichoometric germanide TbIrGe2 exhibits at least two disti…
Transport and magnetic behavior under pressure and high-resolution photoemission studies of Ce2Rh(o.7)Co(0.3)Si3, an alloy on the verge of quantum critical point
K. Mukherjee, Kartik K Iyer, Swapnil Patil +2
We report the influence of external pressure on the temperature dependence of magnetization and electrical resistivity as well as high-resolution photoemission studies for an alloy…
Magnetism of fine particles of Kondo lattices, obtained by high-energy ball-milling
E. V. Sampathkumaran, K. Mukherjee, Kartik K Iyer +2
Despite intense research in the field of strongly correlated electron behavior for the past few decades, there has been very little effort to understand this phenomenon in nano par…
