Non-monotonic pressure dependence of high-field nematicity and magnetism in CeRhIn
Toni Helm, Audrey D. Grockowiak, Fedor F. Balakirev +9
CeRhIn provides a textbook example of quantum criticality in a heavy fermion system: Pressure suppresses local-moment antiferromagnetic (AFM) order and induces superconductivit…
Large Fermi Surface of Heavy Electrons at the Border of Mott Insulating State in NiS2
S. Friedemann, H. Chang, M. B. Gamża +7
One of the early triumphs of quantum physics is the explanation why some materials are metallic whereas others are insulating. While a treatment based on single electron states cor…
Miniature Dilatometer Based upon an AFM Piezocantilever
Liran Wang, George M. Schmiedeshoff, David Earl Graf +4
We report on the development of a sensitive dilatometer based upon a AFM piezocantilever. This dilatometer has been tested at temperatures down to 25 mK and in magnetic fields up t…
Evolution of magnetic interactions in a pressure-induced Jahn-Teller driven magnetic dimensionality switch
S. Ghannadzadeh, J. S. Möller, P. A. Goddard +9
We present the results of high-field magnetization and muon-spin relaxation measurements on the coordination polymer CuF_2(H_2O)_2(pyrazine) in pressures up to 22.5 kbar. We observ…
Pressure Evolution of a Field Induced Fermi Surface Reconstruction and of the Neel Critical Field in CeIn3
K. M. Purcell, D. Graf, M. Kano +12
We report high-pressure skin depth measurements on the heavy fermion material CeIn3 in magnetic fields up to 64 T using a self-resonant tank circuit based on a tunnel diode oscilla…
Angle-dependent magnetoresistance oscillations due to magnetic breakdown orbits
A. F. Bangura, P. A. Goddard, J. Singleton +6
We present experimental evidence for a hitherto unconfirmed type of angle-dependent magnetoresistance oscillation caused by magnetic breakdown. The effect was observed in the organ…
