Breakdown of Anomalous Hall Scaling in Dilute Kondo System
Arnab Bhattacharya, Prashant Singh, Ajay Kumar +4
The confluence of strong electronic correlations and Berry curvature-driven transport constitutes a largely underexplored frontier in quantum materials research, particularly in sy…
Physical properties of RCoAl (R = Gd-Tm, Y) single crystals
Sushma Kumari, Fernando A. Garcia, Juan Schmidt +6
Rare-earth (R) based intermetallic compounds can often exhibit diverse physical properties and distinct magnetic anisotropies. A Notable example are the light rare earth members of…
Metallic d-wave altermagnetism in WFeB: a platform for electrically switchable perpendicular spin-splitter response
Eranga H. Gamage, Zhen Zhang, Subhadip Pradhan +9
We report the synthesis and magnetic characterization of WFeB and identify it as a metallic d-wave altermagnet representative of a broader TiNiSi-type family. Neutron diffraction,…
Magnetic field induced modification of a first-order ferromagnetic transition in Eu2In
Ajay Kumar, Anis Biswas, Trevor A. Tyson +3
We present a comprehensive study of the temperature- and magnetic-field-dependent magnetization, specific heat, and local crystal structure across the first-order ferromagnetic-par…
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…
The influence of Ga doping on magnetic properties, magnetocaloric effect, and electronic structure of pseudo-binary GdZn1-xGax (x = 0-0.1)
Anis Biswas, Ajay Kumar, Prashant Singh +9
We explore the impact of introducing IIIA-group element Ga in place of IIB-group element Zn in binary intermetallic GdZn on its magnetic and magnetocaloric properties, as well as e…
Multiple magnetic interactions and large inverse magnetocaloric effect in TbSi and TbSiGe
Ajay Kumar, Prashant Singh, Andrew Doyle +2
We present a comprehensive investigation of the electronic structure, magnetization, specific heat, and crystallography of TbSi (FeB structure type) and TbSiGe (CrB…
