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 o f LaC82 powder crystals. The magnetic moment as a function of temperat ure shows an overall paramagnetic behaviour. A signal drop can be obse rved at 30 K (zero field cooled curve).
