Orientation-driven route to an intrinsic insulating ferromagnetic state in manganite superlattices
Priyanka Aggarwal, Kirill B. Agapev, Sagar Sarkar +3
Increasing precision in the growth of superlattices sparks hope in applications that may arise from engineering layered structures. Heterostructuring and functionalization of magne…
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…
Persistent half-metallic ferromagnetism in a (111)-oriented manganite superlattice
Fabrizio Cossu, Heung-Sik Kim, Biplab Sanyal +1
Heterostructures of mixed-valence manganites are still under intense scrutiny, due to the occurrence of exotic quantum phenomena linked to electronic correlation and interfacial co…
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)…
Metal-insulator transition at the LaAlO3/SrTiO3 interface revisited: A hybrid functional study
F. Cossu, U. Schwingenschlögl, V. Eyert
We investigate the electronic properties of the LaAlO3/SrTiO3 interface using density functional theory. In contrast to previous studies, which relied on (semi-)local functionals a…
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…
