Magnetism between magnetic adatoms on monolayer NbSe
S. Sarkar, F. Cossu, P. Kumari +4
In this work, we report on an computational study of the electronic and magnetic properties of transition metal adatoms on a monolayer of NbSe. We demonstrate that…
Strain-induced stripe phase in charge ordered single layer NbSe
Fabrizio Cossu, Krisztián Palotás, Sagar Sarkar +2
Charge density waves are ubiquitous phenomena in metallic transition metal dichalcogenides. In NbSe, a triangular structural modulation is coupled to a charge modula…
Unveiling hidden charge density waves in single-layer NbSe by impurities
Fabrizio Cossu, Ali G. Moghaddam, Kyoo Kim +4
We employ {\it{ab-initio}} calculations to investigate the charge density waves in single-layer NbSe, and we explore how they are affected by transition metal atoms. Our calcul…
Fe clusters (Fe, n=1-6) chemisorbed on vacancy defects in graphene: Stability, spin-dipole moment and magnetic anisotropy
Soumyajyoti Haldar, Bhalchandra S. Pujari, Sumanta Bhandary +4
In this work, we have studied the chemical and magnetic interactions of Fe ; n=1-6 clusters with vacancy defects (monovacancy to correlated vacancies with six missing C atoms)…
Surface antiferromagnetism and incipient metal-insulator transition in strained manganite films
F. Cossu, U. Schwingenschlögl, G. Colizzi +2
Using first-principles calculations, we show that the (001) surface of the ferromagnet LaSrMnO under epitaxial compression favors antiferromagnetic ordering in…
