Soft magnetic hysteresis in a dysprosium amide–alkene complex up to 100 kelvin

Abstract Lanthanides have shown magnetic memory at both the atomic 1,2 and molecular 3,4 level. The magnetic remanence temperatures of lanthanide single-molecule magnets can surpass d -transition metal examples 5,6 , and since 2017, energy barriers to magnetic reversal ( U eff ) from 1,237(28) cm –1 to 1,631(25) cm –1 and open magnetic hysteresis loops between 40 K and 80 K have typically been achieved with axial dysprosium(III) bis(cyclopentadienyl) complexes 7–17 . It has been predicted that linear dysprosium(III) compounds could deliver greater m J (the projection of the total angular momentum, J , on a quantization axis labelled z ) state splitting and therefore higher U eff and hysteresis temperatures…
