Size-induced Exchange Bias in Single-phase CoO Nanoparticles
Vikash Sharma, Sudip Pal, Divya Sharma +3
We report exchange bias (EB) in single-phase CoO nanoparticles, where two magnetic phases naturally emerge as the crystallite size decreases from 34.6 to 10.8 nm. The Néel temperat…
Experimental observation of spin glass state in highly disordered quaternary Heusler alloy FeRuMnGa
Shuvankar Gupta, Sudip Chakraborty, Santanu Pakhira +8
The realization of spin-glass (S-G) state in Heusler alloys is very rare despite the presence of inherent structural and elemental disorder in those compounds. Although a few half…
A New Load-based Thermopower Measurement Setup in the Temperature Range of 5 - 330 K
Tarachand, Monika Saxena, Bodhoday Mukherjee +1
This is the report on new development of an automated precision load-based measurement setup for thermoelectric power of different types of samples in the temperature range 5 - 330…
Size-induced structural phase transition at ~6.0 nm from mixed fcc-hcp to purely fcc structure in monodispersed nickel nanoparticles
Tarachand, Vikash Sharma, Jaiveer Singh +5
We have investigated the core issue of atomic lattices in monodispersed Ni nanoparticles (NPs) of sizes 3.8 nm to 10.1 nm using detailed analysis of X-ray diffraction, synchrotron…
Quantum Size Effect Exponential Heat Capacity in 4 nm Natural Nickel Nanolattice
Tarachand Patel, Jaiveer Singh, Satya Sanmukharao Samatham +4
Quantum size effect-induced heat capacity of metal nanoparticles at low temperatures was predicted 79 years ago to be exponential. This, however, has not been reported until date.…
Change-over of carrier type and magneto-transport property in Cu doped Bi2Te3 Topological Insulators
Abhishek Singh, Rahul Singh, A. Lakhani +5
Structural, resistivity, thermoelectric power and magneto-transport properties of Cu doped Bi2Te3 topological insulators have been investigated. The occurrence of the tuning of cha…
