Presence of atomic disorder and its effect on magnetic and electronic properties of NiCrGa half Heusler alloy
Madhusmita Baral, M. K. Chattopadhyay, Aparna Chakrabarti +1
In this work, polycrystalline NiCrGa half Heusler alloy, which is predicted to be half-metallic ferromagnet from first principles calculations, has been synthesized by arc meting t…
Contrasting the magnetic response between magnetic-glass and reentrant spin-glass
S. B. Roy, M. K. Chattopadhyay
Magnetic-glass is a recently identified phenomenon in various classes of magnetic systems undergoing a first order magnetic phase transition. We shall highlight here a few experime…
Surface and interface study of pulsed-laser-deposited off-stoichiometric NiMnSb thin films on Si(100) substrate
S. Rai, M. K. Tiwari, G. S. Lodha +9
We report a detailed study of surface and interface properties of pulsed-laser deposited NiMnSb films on Si (100) substrate as a function of film thickness. As the thickness of fil…
Field induced first order antiferromagnetic to ferromagnetic transition in Al-doped CeFe: a calorimetric investigation
L. S. Sharath Chandra, Kaustav Mukherjee, V. Ganesan +4
Field variation of heat capacity at fixed temperatures is investigated to identify the origin of the field induced first order phase transition in polycrystalline Ce(FeAl…
Kinetic arrest of the first order ferromagnetic to antiferromagnetic transition in Ce(FeRu) : formation of a magnetic-glass
M. K. Chattopadhyay, S. B. Roy, P. Chaddah
We present results of dc magnetization and magnetic relaxation study showing the kinetic arrest of a first order ferromagnetic to antiferromagnetic transition in Ce(FeRu$_…
Unusual transport properties of ferromagnetic Heusler alloy CoTiSn
S. Majumdar, M. K. Chattopadhyay, V. K. Sharma +3
We report results of magnetization, zero field resistivity and magnetoresistance measurements in ferromagnetic Heusler alloy CoTiSn. There is a striking change in the character…
