Observation of magnetic interactions between localized 4f- and itinerant π-electrons in a single crystal of cationic bisphthalocyanine complexes containing diluted spin centres†
Abstract
Magnetic f–π interactions between localized 4f-electrons and itinerant π-electrons have been observed in a single crystal of bisphthalocyaninato yttrium(III)/terbium(III) tetrafluoroborate ([Pc2Y0.95Tb0.05][BF4]) by measuring electrical conductivity of the crystal in the presence of an external magnetic field.
