Fermionic Approach to Elementary Excitations and Magnetization Plateaus in an S=1/2 XX Hybrid Trimer-Dimer Chain
K. S. Chikara, A. K. Bera, A. Kumar +1
We study the elementary excitations and magnetization of a one-dimensional spin-1/2 XX chain comprising trimer-dimer units (the J1-J1-J2-J3-J2 topology) under a transverse magnetic…
Evidence for magnetoelastic coupling and chiral magnetic ground state in quasi-van der Waals tr-CrTe
S. M. Hossain, B. Rai, P. R. Baral +4
Trigonal tr-CrTe is a well-known ferromagnetic material that has recently drawn much attention due to the discovery of zero-field skyrmion state, unusual anomalous Ha…
Magnetic Ground State and Spin Excitations in the 2D Trimerized Collinear-II Lattice Antiferromagnet Li2Ni3P4O14
K. S. Chikara, A. K. Bera, A. Kumar +3
We report the magnetic ground state, spin excitations, and spin Hamiltonian of the 2D spin-1 trimerized Heisenberg antiferromagnet Li2Ni3P4O14. Below the magnetic ordering temperat…
Fermionic Band Dispersions and an Evidence of Cooperon Excitations in a Spin- Trimer Chain
P. Srikanth Patnaik, Snehasish Sen, A. K. Bera +3
We obtain the solution of the Hamiltonian of an antiferromagnetically coupled spin- trimer chain in terms of three bands that host three different species of fermions. While t…
Structural modulation driven Curie temperature enhancement in Cr-doped SrRuO3
Pooja, Bikash Saha, Nitesh Choudhary +4
Strongly correlated system with competing ground states are often poised close to the quantum critical point. External perturbations such as pressure, strain, electric field, and c…
Antiferromagnetic ordering and glassy nature in NASICON type NaFePO(SO)
Manish Kr. Singh, A. K. Bera, Ajay Kumar +2
We investigate crystal structure and magnetic properties including spin relaxation and magnetocaloric effect in NASICON type NaFePO(SO) sample. The Rietveld refinem…
