Title: Heat Capacity Measurements in Pulsed Magnetic Fields

Abstract

The new NHMFL 60T quasi-continuous magnet produces a flat-top field for a period of 100 ms at 60 Tesla, and for longer time at lower fields, e.g. 0.5 s at 45 Tesla. We have developed for the first time the capability to measure heat capacity at very high magnetic fields in the NHMFL 60T quasi-continuous magnet at LANL, using a probe built out of various plastic materials. The field plateau allows us to utilize a heat-pulse method to obtain heat capacity data. Proof-of-principle heat capacity experiments were performed on a variety of correlated electron systems. Both magnet performance characteristics and physical properties of various materials studied hold out a promise of wide application of this new tool.

  • The phase diagram of RKKY spin-glasses is discussed in the light of calorimetric data on three dilute CuMn samples in applied fields, 9kOe less than or equal to H less than or equal to 75 kOe.
  • Magnetic refrigeration is a new technology that potentially offers refrigeration efficiencies > 50% of Carnot, compactness, and high reliability. Studies indicate that approx. 35% of Carnot efficiency is generally the best that is now possible for gas compression/expansion systems and, at that, only for very large plants; for smaller machines, the fraction of Carnot efficiency can become very small, e.g., 1-W refrigerators generally operate at 2 to 8% of Carnot efficiency. For magnetic refrigerators, the compression/expansion processes are replaced by a cycle involving the application/removal of a magnetic field to either a paramagnetic or ferromagnetic material (generally, paramagnets are usedmore » below approx. 20K and ferromagnets above). The thermodynamic cycles in gas and magnetic systems are analogous. Central to the development of magnetic refrigerators is the characterization of magnetic working substances. Among the key properties for which we require data are the heat capacity (from which we derive the entropy) and the thermal conductivity as functions of temperature and magnetic field. Accordingly, at the Los Alamos National Laboratory, we have designed and constructed an apparatus to make measurements of these quantities over the range 1 to 300 K at fields up to 9 T. We describe the methodology of these measurements, the versatile apparatus for making them, and results on GdNi, the first sample measured.« less
  • The compound CeRhSb is a mixed valent Ce-based compound which shows a gap in the electronic density of states at low temperatures. The gap manifests by a rise in electrical resistivity{emdash}below about 8 K from which the gap energy is estimated to be about 4 K. We have carried out heat capacity measurements on this compound in various applied fields up to 9.85 T. The magnetic contribution to the heat capacity, {Delta}C, is found to have a maximum in {Delta}C/T vs T at 10 K, below which {Delta}C/T is linear with T. This is attributed to the fact that belowmore » this temperature, in the gapped state, the electronic density of states decreases linearly with decreasing temperature. On application of a magnetic field, the electronic specific heat coefficient {gamma} in the gapped state increases by {approximately}4mJ/molK{sup 2}. The maximum in {Delta}C/T vs T is observed in all fields, which shifts to lower temperatures {approximately}1K at 5.32 T and raises again at 9.85 T to about the same values as at H=0T. This suggests that the gap exists for all fields up to 9.85 T. Above 10 K, in the mixed-valent state, {Delta}C/T vs T decreases with increasing temperature in zero field. There is hardly any effect of application of field in the mixed-valent state. We have also carried out magnetoresistance measurements on CeRhSb up to fields of 5.5 T at 2, 4.5, 10, 20, and 30 K. The magnetoresistance in CeRhSb is positive at temperatures of 4.5 K and above, in applied fields up to 5.5 T. At 5.5 T, the magnetoresistance is maximum at 4.5 K (6{percent}) and decreases with increasing temperature. The observation of the maximum is consistent with the observation of a maximum in {Delta}C/T vs T and is due to a change in the density of states. At a temperature of 2 K, a negative magnetoresistance is observed for magnetic fields greater than {approximately}3.5T which suggests reduction in the gap. {copyright} {ital 1997} {ital The American Physical Society}« less
  • The establishment of the National High Magnetic Field Laboratory (NHMFL) in Tallahassee, FL and at the Los Alamos National Laboratory NM will provide the US with a unique opportunity to explore new scientific phenomena in magnetic fields that are significantly higher than presently available. The facilities to be developed within the new NHMFL will include continuous fields to 45 tesla and pulsed fields to 200 tesla. The authors review some of the promising new areas of the physics of quantum fluids and solids, superconductivity, materials science and engineering, and advanced technologies that will be able to be studied and developedmore » at the new facility. An overview of the scope of the laboratories facilities, planned scheduling and the proposed timetable for the installation of magnet systems for this new national user facility is presented.« less
