Noncentrosymmetric (NCS) materials feature an exciting array of functionalities such as
nonlinear optical (NLO) responses and topological spin textures (skyrmions). While NLO …

A magnetic skyrmion is a particle-like spin swirling object with a nontrivial topology that
holds great promise for next-generation information carriers in high-performance spintronic …

Skyrmions are nano-scale quasi-particles with topological protection, which have potential
applications in next-generation spintronics-based information storage. Numerous papers …

In the last two decades, significant progress has been made in combining ferroelectricity and
magnetism in the same material. Usually, magnetism and ferroelectricity were thought of as …

Using ab initio density functional theory with static mean-field correlations, we calculate the
Heisenberg and Dzyaloshinskii-Moriya interactions (DMI) for an atomistic spin Hamiltonian …

Transition-metal atoms with d electrons sometimes form clusters in crystals, which
significantly affect the physical properties. Such a cluster formation frequently accompanies …

In the lacunar spinels, with the formula AB4X8, transition-metal ions form tightly bound B4
clusters resulting in exotic physical properties such as the stabilization of Néel-type skyrmion …

We investigate theoretically magnetoentropic signatures of the crystal phase of magnetic
skyrmions of various kinds, commonly appearing in two dimensions, viz., Néel, Bloch, and …

Magnetic skyrmions, which are topologically distinct magnetic spin textures, are gaining
increased attention for their unique physical properties and potential applications in …

This paper aims to review the physical properties and crystal chemistry of the family of
correlated quantum materials AM4Q8 (A= Ga, Ge; M= V, Nb, Ta, Mo; Q= S, Se). These …
