From Complex Magnetic Ground States to Magnetocaloric Effects: A Review of Rare Earth RIn Intermetallic Compounds
Anis Biswas, Ajay Kumar, Prashant Singh +1
R2In (R = rare earth) intermetallics exhibit unusual magnetic and magnetocaloric properties, driven by subtle electronic effects, lattice distortions, and spin-lattice coupling. Mo…
Non-trivial critical behavior at the magnetic transitions: A case study of SmPd
Ajay Kumar, Anis Biswas, Y. Mudryk
We present a comprehensive analysis of the critical behavior of SmPd in the vicinity of its second-order magnetoelastic transition at K. The critical exp…
Unconventional magnetic glassiness in non-centrosymmetric SmPd: Interplay of magnetic frustration, long-range order, and frozen domains
Ajay Kumar, Anis Biswas, Yaroslav Mudryk
We present a comprehensive investigation of the intricate spin dynamics in the non-centrosymmetric compound SmPd, revealing the coexistence of spin glass, domain glass, and…
Fermi surface nesting driven anomalous Hall effect in magnetically frustrated Mn_2PdIn
Afsar Ahmed, Arnab Bhattacharya, Prashant Singh +5
Noncollinear magnets with near-zero net magnetization and nontrivial bulk electronic topology hold significant promise for spintronic applications, though their scarcity necessitat…
Large anomalous Hall effect and \textit{A}-phase in hexagonal polar magnet GdNiSn
Arnab Bhattacharya, Afsar Ahmed, Apurba Dutta +4
While recent theoretical studies have positioned noncollinear polar magnets with symmetry as compelling candidates for realizing topological magnetic phases and substantia…
Stability of the first-order character of phase transition in HoCo
Ajay Kumar, Anis Biswas, Yaroslav Mudryk
HoCo exhibits a giant magnetocaloric (MC) effect at its first-order magnetostructural phase transition around 77~K, and understanding the thermodynamic nature of this transitio…
