Transition from AFM Spin Canting to Spin Glass–AFM Exchange as Particle Size Decreases in LaFeO3

Publicada el 17 mayo, 2023 por agullo

In this work, we have studied structural and magnetic properties of LaFeO3 as a function of the particle size d, from bulk (d >> 1 μm) to nanoscale (d ≈ 30 nm). A large number of twins were observed for … Sigue leyendo →

Coexistence of Two Spin Frustration Pathways in the Quantum Spin Liquid Ca10Cr7O28

Publicada el 21 octubre, 2022 por agullo

Kagome antiferromagnetic lattices are of high interest because the geometric frustration is expected to give rise to highly degenerated ground states that may host exotic properties such as quantum spin liquid (QSL). Ca10Cr7O28 has been reported to display all the … Sigue leyendo →

Spatially resolved MoOx phases by laser localized oxidation of MoO2

Publicada el 20 abril, 2021 por agullo

MoO2 thin films were subjected to a laser localized oxidation process that allowed to obtain different well defined MoOx phases. In particular, spatially resolved MoO2, α-MoO3, β-MoO3, amorphous a-MoO3, and Mo4O11 regions were obtained as a function of the laser … Sigue leyendo →
