Coexistence of orbital and quantum critical magnetoresistance in FeSeS
S. Licciardello, N. Maksimovic, J. Ayres +9
The recent discovery of a non-magnetic nematic quantum critical point (QCP) in the iron chalcogenide family FeSeS has raised the prospect of investigating, in isolati…
Negative thermal expansion in the plateau state of a magnetically-frustrated spinel
L. Rossi, A. Bobel, S. Wiedmann +6
We report on negative thermal expansion (NTE) in the high-field, half-magnetization plateau phase of the frustrated magnetic insulator CdCr2O4. Using dilatometry, we precisely map…
A low-temperature scanning tunneling microscope capable of microscopy and spectroscopy in a Bitter magnet at up to 34 T
W. Tao, S. Singh, L. Rossi +7
We present the design and performance of a cryogenic scanning tunneling microscope (STM) which operates inside a water-cooled Bitter magnet, which can attain a magnetic field of up…
Temperature and Field Dependence of Magnetic Domains in LaSrMnO
B. Bryant, Y. Moritomo, Y. Tokura +1
Colossal magnetoresistance and field-induced ferromagnetism are well documented in manganite compounds. Since domain wall resistance contributes to magnetoresistance, data on the t…
Spin wave imaging in atomically designed nanomagnets
A. Spinelli, B. Bryant, F. Delgado +2
The spin dynamics of all ferromagnetic materials are governed by two types of collective excitations: spin waves and domain walls. The fundamental processes underlying these collec…
Exploring the phase diagram of the two-impurity Kondo problem
A. Spinelli, M. Gerrits, R. Toskovic +3
A system of two exchange-coupled Kondo impurities in a magnetic field gives rise to a rich phase space hosting a multitude of correlated phenomena. Magnetic atoms on surfaces probe…
