Metamagnetism and the Fifth Order Susceptibility in UPt3
B. S. Shivaram, Brian Dorsey, D. G. Hinks +1
An enhanced susceptibility is a natural consequence of the "heavy fermion" (HF) state rendering the possibility of measurably large nonlinear susceptibilities. In recent work a uni…
Observation of a Zeeman Induced Lifshitz Transition in URu2Si2
B. S. Shivaram, V. W. Ulrich, D. G. Hinks
High resolution longitudinal sound velocity measurements in a magnetic field performed at T tending to zero in URu2Si2 reveal a second signature at a field BLT in addition to the s…
Universality in the Magnetic Response of Metamagnetic Metals
B. S. Shivaram, D. G. Hinks, M. B. Maple +2
We report in this paper, measurements of the nonlinear susceptibility χ_sub3(T) in the metamagnetic heavy fermion (HF) compound UPt3. At high temperatures, χ_sub3(T) < 0 and small.…
Universal features in the photoemission spectroscopy of high temperature superconductors
J. Zhao, U. Chatterjee, D. Ai +9
The energy gap for electronic excitations is one of the most important characteristics of the superconducting state, as it directly refects the pairing of electrons. In the copper-…
Low Field Magnetic Susceptibility and the Hidden Order Transition in URu2Si2
B. S. Shivaram, D. G. Hinks
Despite several decades of both experimental and theoretical work the nature of the hidden order transition at THO = 17.5 K in URu2Si2 remains enigmatic. We report here low field D…
H-T phase diagram of the metamagnetic transition in , measured in high d. c. magnetic fields
A. Suslov, J. B. Ketterson, D. G. Hinks +1
We have studied the ultrasonic velocity and ac susceptibility of in d. c. magnetic fields up to 45T. A significant difference between the constructed H-T phase diagram…
