Detection of nontrivial topology driven by charge density wave in a semi-Dirac metal
Rafiqul Alam, Prasun Boyal, Shubhankar Roy +6
The presence of electron correlations in a system with topological order can lead to exotic ground states. Considering single crystals of LaAgSb2 which has a square net crystal str…
Unusual magnetotransport and anomalous Hall effect in quasi-two-dimensional van der Waals ferromagnet FeGeTe
Riju Pal, Buddhadeb Pal, Suchanda Mondal +2
FeGeTe, an itinerant vdW ferromagnet (FM) having Curie temperature (T) close to room temperature ( K), exhibits another transition (T 120 K) whe…
Charge density wave induced nodal lines in LaTe
Shuvam Sarkar, Joydipto Bhattacharya, Pampa Sadhukhan +11
LaTe is a noncentrosymmetric (NC) material with time reversal (TR) symmetry in which the charge density wave (CDW) is hosted by the Te bilayers. Here, we show that LaTe hos…
Weak antilocalization effect and triply degenerate state in Cu-doped CaAuAs
Sudip Malick, Arup Ghosh, Chanchal K. Barman +4
The effect of 50\% Cu doping at the Au site in the topological Dirac semimetal CaAuAs is investigated through electronic band structure calculations, electrical resistivity, and ma…
Anomalous magnetic properties of quasi two-dimensional van der Waals ferromagnet Fe4GeTe2
Suchanda Mondal, Prabhat Mandal
We have studied the magnetic properties of quasi two-dimensional itinerant ferromagnet FeGeTe as functions of temperature and magnetic field () with field parallel to th…
Electric-field-driven resistive transition in multiferroic SrCoFeO/SrCoFeOcomposite
Shubhankar Mishra, Chandan K. Ghosh, Aditi Sahoo +3
We report observation of electric-field-driven resistive transition at a characteristic threshold field across a temperature range 10-200 K in an off-stoichiometric com…
