TL;DR
This study uses resonant soft X-ray scattering to show that ferromagnetism enhances CE-type spin ordering in (Pr,Ca)MnO$_3$, revealing a cooperative interaction that influences colossal magnetoresistance.
Contribution
It uncovers the ferromagnetic enhancement of CE-type spin ordering in (Pr,Ca)MnO$_3$, demonstrating a cooperative interplay contrasting previous understanding.
Findings
CE-type spin ordering is stabilized below the canted antiferromagnetic transition temperature.
Ferromagnetism in the insulating state enhances CE-type spin ordering.
The interplay between ferromagnetism and spin ordering is cooperative, not competitive.
Abstract
We present resonant soft X-ray scattering (RSXS) results from small band width manganites (Pr,Ca)MnO, which show that the CE-type spin ordering (SO) at the phase boundary is stabilized only below the canted antiferromagnetic transition temperature and enhanced by ferromagnetism in the macroscopically insulating state (FM-I). Our results reveal the fragility of the CE-type ordering that underpins the colossal magnetoresistance (CMR) effect in this system, as well as an unexpected cooperative interplay between FM-I and CE-type SO which is in contrast to the competitive interplay between the ferromagnetic metallic (FM-M) state and CE-type ordering.
