Molar magnetic susceptibility () measurement have been done on powdered sample in the temperature range 300-1000K. At higher temperature, studied materials exhibit Curie-Weiss law with negative value of paramagnetic Curie temperature indicating antiferromagnetic ordering at lower temperature.<br /> &nbsp;</p> https://ultraphysicalsciences.org/paper/939/ magnetic susceptibility Rare-earth nickelates Curie temperature.
