Competing effects of Hund's splitting and symmetry-breaking perturbations on electronic order in Pb $_{1 - x}$ Sn $_{x}$ Te

Sarbajaya Kundu, Vikram Tripathi

We study the effect of a uniform external magnetization on p-wave superconductivity on the (001) surface of the crystalline topological insulator(TCI) Pb $_{1 - x}$ Sn $_{x}$ Te. It was…

Magnetic anisotropy of the alkali iridate Na $_{2}$ IrO $_{3}$ at high magnetic fields: evidence for strong ferromagnetic Kitaev correlations

Sitikantha. D Das, Sarbajaya Kundu, Zengwei Zhu +10

The magnetic field response of the Mott-insulating honeycomb iridate Na $_{2}$ IrO $_{3}$ is investigated using torque magnetometry measurements in magnetic fields up to 60 tesla. A p…

Semiclassical theory for liquid-like behaviour of the frustrated magnet $Ca_{10} Cr_{7} O_{28}$

Sounak Biswas, Kedar Damle

We identify the low energy effective Hamiltonian that is expected to describe the low temperature properties of the frustrated magnet $\mathrm{Ca}_{10}\mathrm{Cr}_{7}\mathrm{O}_{28…

Extraordinarily large intrinsic magnetodielectric coupling of Tb member within the Haldane spin-chain family, R2BaNiO5

Sanjay Kumar Upadhyay, P. L. Paulose, E. V. Sampathkumaran

The Haldane spin-chain compound, Tb2BaNiO5, has been known to order antiferromagnetically below (T_N= ) 63 K. The present magnetic studies on the polycrystals bring out that there…

Bose-Einstein condensation of triplons in the S=1 tetramer antiferromagnet K2Ni2(MoO4)3: A compound close to quantum critical point

B. Koteswararao, P. Khuntia, R. Kumar +5

The structure of K2Ni2(MoO4)3 consists of S=1 tetramers formed by Ni^{2+} ions. The magnetic susceptibility chi(T) and specific heat Cp(T) data on a single crystal show a broad max…

Quasi Static Remanence in Dzyaloshinskii-Moriya Interaction driven Weak Ferromagnets and Piezomagnets

Namrata Pattnayak, Arpan Bhattacharyya, A. K. Nigam +2

We explore remanent magnetization ( $μ$ ) as a function of time and temperature, in a variety of rhombohedral antiferromagnets (AFM) which are also weak ferromagnets (WFM) and piezom…

Electric field control of emergent electrodynamics in quantum spin ice

Étienne Lantagne-Hurtubise, Subhro Bhattacharjee, Roderich Moessner

We study the coupling between conventional (Maxwell) and emergent electrodynamics in quantum spin ice, a 3+1-dimensional $U (1)$ quantum spin liquid. We find that a uniform electric…
