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…
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…
Sharp magnetization step across the ferromagnetic to antiferromagnetic transition in doped-CeFe alloys
S. B. Roy, M. K. Chattopadhyay, P. Chaddah +1
Very sharp magnetization step is observed across the field induced antiferromagnetic to ferromagnetic transition in various doped-CeFe alloys, when the measurement is performed…
First order magnetic transition in CeFe alloys: Phase-coexistence and metastability
S. B. Roy, G. K. Perkins, M. K. Chattopadhyay +5
First order ferromagnetic (FM) to antiferromagnetic (AFM) phase transition in doped-CeFe alloys is studied with micro-Hall probe technique. Clear visual evidence of magnetic ph…
