Crystal structure and magnetic properties of spin- frustrated two-leg ladder compounds (CHN)Cu (= Cl and Br)
P. Biswal, S. Guchhait, S. Ghosh +5
We have successfully synthesized single crystals, solved the crystal structure, and studied the magnetic properties of a new family of copper halides (CHN)Cu…
Singlet quantum phases and magnetization of the frustrated spin-1/2 ladder with ferromagnetic (F) exchange in legs and alternating F-AF exchange in rungs
Monalisa Chatterjee, Manoranjan Kumar, Zoltán G. Soos
The magnetization is used to identify three singlet quantum phases of the ladder with isotropic exchange interactions. The Dimer phase with frustrated F exchanges in rungs a…
Magnetic plateaus and jumps in a spin-1/2 ladder with alternate Ising-Heisenberg rungs: a field dependent study
Sk Saniur Rahaman, Manoranjan Kumar, Shaon Sahoo
We study a frustrated two-leg spin-1/2 ladder with alternate Ising and isotropic Heisenberg rung exchange interactions, whereas, interactions along legs and diagonals are Ising typ…
Rare observation of spin-gapless semiconducting characteristics and related band topology of quaternary Heusler alloy CoFeMnSn
Shuvankar Gupta, Jyotirmoy Sau, Manoranjan Kumar +1
In this paper, we report the theoretical investigation and experimental realization of a new spin-gapless semiconductor (SGSs) compound CoFeMnSn belonging to the family of quaterna…
Proximate Dirac spin liquid in honeycomb lattice - XXZ model: Numerical study and application to cobaltates
Anjishnu Bose, Manodip Routh, Sreekar Voleti +4
Recent theoretical and experimental work suggest that the honeycomb cobaltates, initially proposed as candidate Kitaev quantum magnets, are in fact described by a pseudospin-…
Emergent many-body composite excitations of interacting spin-1/2 trimers
A. K. Bera, S. M. Yusuf, S. K. Saha +4
Understanding exotic forms of magnetism in quantum spin systems is an emergent topic of modern condensed matter physics. Quantum dynamics can be described by particle-like carriers…
