Positive Temperature Coefficient of Anisotropy due to $d^{6} L$ Groundstate in $ε$ -Fe $_{2}$ O $_{3}$

Rachel Nickel, Kurt Kummer, Johan van Lierop

Positive anisotropy temperature coefficients ( $d K / d T > 0$ ) usually arise from hybridization between magnetic 3d states and strongly spin-orbit-coupled (SOC) subsystems. Yet $ε$ -Fe$_2…

Temperature and field evolution of site-dependent magnetism in $ε$ -Fe $_{2}$ O $_{3}$ nanoparticles

Richard Jones, Rachel Nickel, Palash K. Manna +2

8~nm epsilon-Fe2O3 nanoparticles exhibit a spin reorientation transition that begins at 150 K which is a hallmark of this unique iron-oxide polymorph. We find that the change from…
