Electronic and Nuclear Magnetism in Platinum-Iron at Ultralow Temperatures

I n Februarx 1996, physicists at the University of Bayreuth claimed a world record for producing the lowest temperature yet achieved when they announced the results of their work with platinum. They cooled 31.4 grams of plat inum to 2 millionths of a degree Celsius above absolute zero temperature, -273.15"C. I n this paper they describe the theory and the practical work behind this accomplishme...

Nuclear Magnetism in Solid Methane

For more than 30 years, the observation of nuclear magnetic interactions in solid methane has given valuable information on the reorientational dynamics of its molecules. Recently, measurements of some basic properties of nuclear absorption lineshapes, such as the. integrated intensity and the second moment, have revealed the rates at which the populations of various molecular orientational sta...

Electronic structure and magnetism of Fe1ÀxPdx alloys

An ab initio linearized augmented plane-wave method has been employed to calculate the electronic and magnetic structures of both face-centered-cubic and body-centered-cubic Fe12xPdx alloys with x50.25, 0.50, and 0.75, respectively. Decreasing the Pd content in Fe12xPdx alloy from x51, the magnetic ordering of fcc Fe12xPdx changes from paramagnetism to ferromagnetism, ferrimagnetism, and finall...

Aspects of Frustrated Magnetism and Topological Order

In the first part we study O(N) spins on geometrically frustrated pyrochlore and planar pyrochlore lattices. For classical spins the strong frustration causes a lack of ordering for N 6= 2 at all temperatures. Nevertheless at low temperatures the system is strongly correlated. We find degrees of freedom that are relevant in this regime and find that the correlations are dipolar up to distance ∼...
