Magnetic susceptibility of molecular cryocrystals doped with oxygen impurity

Abstract

The magnetic susceptibility of N2−O2(0.5–10% O2) and CO−O2 (0.1–2% O2) in the temperature range 1–50 K has been measured. It was found that the low temperature magnetic susceptibility vs T deviates markedly from the Curie law. The magnetic susceptibility of the weak solutions was calculated in cluster approximation taking into accoun the exchange interaction and the spin-figure interaction. It is shown that the data on the magnetic susceptibility may be used to analize the character of the positional and orientational short-range order in the solid solutions.
