TL;DR
This study investigates how confining antiferromagnetic CoO within porous glass affects its magnetic phase transition, revealing a lowered Néel temperature and diminished magnetic moment compared to bulk CoO.
Contribution
It provides the first neutron diffraction analysis of magnetic phase transitions in CoO confined in porous glass, highlighting the effects of confinement on magnetic properties.
Findings
Decreased Néel temperature in confined CoO
Reduced magnetic moment compared to bulk
Continuous magnetic phase transition observed
Abstract
Neutron diffraction studies of antiferromagnetic CoO confined to a vycor type porous glass demonstrate a continuous magnetic phase transition with a decreased N\'eel temperature and reduced magnetic moment as compared with the bulk.
