Abstract

Magnetization Measurements of LaC₈₂ Powder Crystals

Magnetic susceptibility and superconductivity in exohedral fullerenes are wellknown. Advances in production and purification techniques led to macroscopic amounts of the endohedral metallofullerene LaC₈₂. Laser desorption mass spectroscopy measurements displayed the purity of the material. In this paper we present a dc-magnetization investigation of LaC₈₂ powder crystals. The magnetic moment as a function of temperature shows an overall paramagnetic behaviour. A signal drop can be observed at 30 K (zero field cooled curve).
