Magnetization, dielectric and thermal studies in the double perovskite polycrystalline compound Tm2CoMnO6
A. Banerjee, Gangadhar Das, V. Rajaji +2
We report here a comprehensive study on structural, magnetic, caloric and electronic properties of the monoclinic phase of double perovskite compound Tm2CoMnO6 (TCMO) in its polycr…
Unconventional topological phase transition from semimetal to insulator in SnBi2Te4: Role of anomalous thermal expansion
T. K. Dalui, B. Das, C. K. Barman +8
We propose SnBi2Te4 to be a novel candidate material exhibiting temperature (T) mediated transitions between rich topological phases. From a combined theoretical and experimental s…
Two-band conduction as a pathway to non-linear Hall effect and unsaturated negative magnetoresistance in the martensitic compound GdPd2Bi
Snehashish Chatterjee, Saurav Giri, Subham Majumdar +9
The present work aims to address the electronic and magnetic properties of the intermetallic compound GdPdBi through a comprehensive study of the structural, magnetic, electric…
Self organized criticality of magnetic avalanches in disordered ferrimagnetic material
Suman Mondal, Mintu Karmakar, Prabir Dutta +3
We observe multiple step-like jumps in a Dy-Fe-Ga-based ferrimagnetic alloy in its magnetic hysteresis curve at 2 K. The observed jumps have a stochastic character with respect to…
Evidence of exchange-striction and charge disproportionation in the magneto-electric material Ni3TeO6
Mohamad Numan, Gangadhar Das, Md Salman Khan +5
The chiral magneto-electric compound Ni3TeO6 is investigated through temperature-dependent synchrotron-based powder x-ray diffraction and x-ray absorption spectroscopy between 15 t…
Observation of Griffiths-like phase in the quaternary Heusler compound NiFeTiSn
Snehashish Chatterjee, Saurav Giri, Subham Majumdar +3
The quaternary Heusler compound NiFeTiSn can be considered to be derived from the exotic pseudogap-compound Fe2TiSn by the replacement of one Fe atom by Ni. In contrast to Fe2TiSn,…
