First-principles calculations and experimental studies on Co2FeGe Heusler alloy nanoparticles for spintronics applications
Aquil Ahmad, S. K. Srivastava, A. K. Das
Here, we report the synthesis and physical properties of Co2FeGe (CFG) Heusler alloy (HA) nanoparticles (NPs). The NPs of size 23 nm are prepared using the co-precipitation method.…
The role of substrate bias and nitrogen doping on the structural evolution and local elastic modulus of diamond-like carbon films
S. R. Polaki, K. Ganesan, S. K. Srivastava +2
Diamond-like carbon (DLC) films are synthesized on Si using plasma enhanced chemical vapor deposition. The role of substrate bias and nitrogen doping on the structural evolution an…
Magnetic instability and hybridization in CeFe on substituting Cr, Ag and Au for Fe
Rakesh Das, Mukul Gupta, S. K. Srivastava
Hybridization between Ce and conduction states has been speculatively known to be one of the mechanisms responsible for magnetic instability of the ferromagnetic ground sta…
Evidence of quantum Griffiths phase in Ni_{1-x}V_x nanoalloys
P. Swain, Suneel K. Srivastava, Sanjeev K. Srivastava
Metallic NiV alloys are known to exhibit a ferromagnetic to paramagnetic disordered quantum phase transition (QPT) at the critical concentration 0.114 in bul…
Magnetic Property of Rutile Ti0.94A0.06O2 (A=Li, Mg, K) Compounds
S. K. Srivastava, M. Brahma, B. Brahma +1
Our purpose is to study role of ionic radii of non-magnetic dopants; Li+ (0.68 Å), Mg2+ (0.72 Å) and K+ (1.38 Å) on the magnetic property of rutile TiO2 compound. The Ti0.94A0.06O2…
