Abstract: Abstract Nanoparticles cobalt ferrite, vacancies defective through vanadium substitution for iron, were synthesized by a sol-gel method. Two systems CoFe2-xVxO4 (0.0 ≤ x ≤ 0.25) and CoFe2-1.67xVxO4 (x = 0.1, 0.2) were prepared. The crystal structure, microstructure and magnetic properties were… read more here.

Abstract: In this Letter, we describe quantitative magnetic imaging of superconducting vortices in RbEuFe_{4}As_{4} in order to investigate the unique interplay between the magnetic and superconducting sublattices. Our scanning Hall microscopy data reveal a pronounced suppression… read more here.
