Susceptibility Measurements of Impurity-Helium Condensates Containing Magnetic Impurities Conference Paper uri icon

abstract

  • The magnetic susceptibilities of impurity-helium condensates (IHCs), containing nanocrystals of molecular oxygen and atomic nitrogen free radicals embedded in molecular N2 have been measured via a SQUID magnetometer in the temperature range between 1.1 and 2.1 K. The susceptibilities of the samples containing nitrogen atoms followed Curie-Weiss behavior with very small Weiss temperatures ranging from 0 to -0.4 K. The behavior of samples composed of O2 nanocrystals deviated sharply from results for bulk solid. The susceptibilities of the samples were 102 larger than for bulk solid O2 and showed Curie-Weiss behavior with a Weiss temperature in the range from -4.5 K to -5 K. This result is qualitatively consistent with results obtained in other laboratories for O2 confined in restricted geometries. 2009 IOP Publishing Ltd.
