Quadratic heat capacity and high-field magnetic phases of V5S8
C. A. Sonego, P. M. T. Vianez, H. Li +4
We report the observation of an unexpected quadratic temperature dependence of the heat capacity in the vanadium sulphide metal V5S8 at low temperatures which is independent of app…
Au-Ge alloys for wide-range low-temperature on-chip thermometry
J. R. A. Dann, P. C. Verpoort, J. Ferreira de Oliveira +4
We present results of a Au-Ge alloy that is useful as a resistance-based thermometer from room temperature down to at least \SI{0.2}{\kelvin}. Over a wide range, the electrical res…
Quantum Critical Phenomena in a Compressible Displacive Ferroelectric
M J Coak, C R S Haines, C Liu +3
The dielectric and magnetic polarizations of quantum paraelectrics and paramagnetic materials have in many cases been found to initially increase with increasing thermal disorder a…
Superconductivity in the vicinity of a ferroelectric quantum phase transition
S. E. Rowley, C. Enderlein, J. Ferreira de Oliveira +4
Superconductivity has been observed in doped SrTiO at charge-carrier densities below 10 cm, where the density of states at the Fermi level of the itinerant electr…
Quantum percolation phase transition and magneto-electric dipole glass in hexagonal ferrites
S. E. Rowley, T. Vojta, A. T. Jones +7
Hexagonal ferrites do not only have enormous commercial impact (£2 billion/year in sales) due to applications that include ultra-high density memories, credit card stripes, magneti…
Prospects and Applications Near Ferroelectric Quantum Phase Transitions
P. Chandra, G. G. Lonzarich, S. E. Rowley +1
The emergence of complex and fascinating states of quantum matter in the neighborhood of zero temperature phase transitions suggests that such quantum phenomena should be studied i…
Hidden fluctuations close to a quantum bicritical point
Corentin Morice, Premala Chandra, Stephen E. Rowley +2
In this paper we describe physical properties arising in the vicinity of two coupled quantum phase transitions. We consider a phenomenological model based on two scalar order param…
Quantum Critical Point study in Multiferroic Hexaferrites: BaFe12O19, SrFe12O19, and PbFe3Ga9O19 -- Verification of the Khmelnitskii Theory
S. E. Rowley, Yi-sheng Chai, Shi-peng Shen +4
BaFe12O19 is a popular M-type hexaferrite with T(Neel) = 720 K of enormous commercial value (3 billion dollars/year). It exhibits an incipient ferroelectric phase transition (in vi…
Quantum criticality in a uniaxial organic ferroelectric
S. E. Rowley, M. Hadjimichael, M. N. Ali +4
Tris-sarcosine calcium chloride (TSCC) is a highly uniaxial ferroelectric with a Curie temperature of approximately 130K. By suppressing ferroelectricity with bromine substitution…
Heavy Fermion Quantum Criticality and Destruction of the Kondo Effect in a Nickel Oxypnictide
Yongkang Luo, Leonid Pourovskii, S. E. Rowley +8
A quantum critical point arises at a continuous transformation between distinct phases of matter at zero temperature. Studies in antiferromagnetic heavy fermion materials have reve…
Enhancement of the magnetocaloric effect driven by changes in the crystal structure of Al doped GGG, Gd3Ga5-xAlxO12 (0 < x < 5)
A. C. Sackville Hamilton, G. I. Lampronti, S. E. Rowley +1
The Gd3Ga5-xAlxO12 (0 < x < 5) solid solution has been prepared using ceramic synthesis routes and the structural and magnetic properties investigated using X-ray diffraction, magn…
Transport and Thermodynamic Evidence for a Marginal Fermi Liquid State in ZrZn
Mike Sutherland, R. P. Smith, N. Marcano +7
Measurements of low temperature transport and thermodynamic properties have been used to characterize the non-Fermi liquid state of the itinerant ferromagnet ZrZn. We observe a…
