Sign Reversal of anisotropic magnetoresistance in La0.7Ca0.3MnO3/STO ultrathin films
Himanshu Sharma, A. Tulapurkar, C. V. Tomy
We present the observation of strain induced sign reversal of anisotropic magnetoresistance (AMR) in LCMO (LCMO) ultrathin films (thickness 4 nm) deposited on STO (001) substrate (…
Magneto-Seebeck effect in spin-valve with in-plane thermal gradient
S. Jain, D. D. Lam, A. Bose +5
We present measurements of magneto-Seebeck effect on a spin valve with in-plane thermal gradient. We measured open circuit voltage and short circuit current by applying a temperatu…
Evidence of surface superconductivity and multi-quanta vortex states in a weakly-pinned single crystal of Ca3Ir4Sn13
Santosh Kumar, Ravi P. Singh, A. Thamizhavel +2
We report here the observation of anomalous paramagnetic signal(s) in the isofield field-cooled cool-down magnetization scans (MFCC(T)) recorded for a single crystal of a low Tc su…
Dual role of an ac driving force and the underlying two distinct order-disorder transitions in the vortex phase diagram of Ca3Ir4Sn13
Santosh Kumar, Ravi P. Singh, A. Thamizhavel +2
We present distinct demarcation of the Bragg glass (BG) to multi-domain vortex glass (VG) transition line and the eventual amorphization of the VG phase in a weakly pinned single c…
Growth and angular dependent resistivity of Nb2Pd0.73S5.7 superconducting single crystals fiber
Anil K. Yadav, Himanshu Sharma, Ajay D. Thakur +1
We report the growth of Nb2Pd0.73S5.7 superconducting single crystal fibers via slow cooling solid state reaction method. Superconducting transition temperature (Tc ~ 6.5K) is conf…
Effect of nominal substitution of transition metals for excess Fe in Fe_{1+x}Se superconductor
Anil K Yadav, Santosh Kumar, Anup V Sanchela +2
Taking cue from the increase in the superconducting transition temperature (Tc) of Fe1+xSe via nominal (2 wt%) substitution of Cr instead of excess Fe, we have now extended our stu…
