Extremely Weakly Interacting $\Delta S_z = 0$ and $\Delta S_z = 1$ Excitations and Evidence for Fractional Quantization in a Magnetization Plateau: CeSb

Autor: LaBarre, Patrick G., Kuthanazhi, Brinda, Abel, Caiden, Canfield, Paul C., Ramirez, Arthur P.

Publikováno v: Phys. Rev. Lett. 125, 247203 (2020)

The plateau at 1/3 of the saturation magnetization, $M_s$, in the metamagnet CeSb is accompanied by a state of ferromagnetic layers of spins in an up-up-down sequence. We measured $M$ and the specific heat, $C$, in the plateau, spin wave analyses of

Probing the Electronic Structure of Graphene Near and Far from the Fermi Level via Planar Tunneling Spectroscopy

Autor: Davenport, John L., Ge, Zhehao, Liu, Junyan, Nuñez-Lobato, Carlos, Moon, Seongphill, Lu, Zhengguang, Quezada, Eberth A., Hellier, Kaitlin, LaBarre, Patrick G., Taniguchi, Takashi, Watanabe, Kenji, Carter, Sue, Ramirez, Arthur P., Smirnov, Dmitry, Velasco Jr, Jairo

Publikováno v: Appl. Phys. Lett. 115, 163504 (2019)

Scanning tunneling spectroscopy (STS) has yielded significant insight on the electronic structure of graphene and other two-dimensional (2D) materials. STS directly measures a fundamental and directly calculable quantity: the single particle density

Mini Volume Collapse as Evidence for a 3-Body Magnetic Polaron in $Sm_{1-x}Eu_xS$

Autor: Schaller, Daniel, LaBarre, Patrick G., Besara, Tiglet, Bucher, Ernst, Siegrist, Theo, Ramirez, Arthur P.

Publikováno v: Phys. Rev. Materials 3, 104602 (2019)

Samarium sulfide (SmS) is a non-magnetic narrow-gap (0.06 eV) semiconductor which undergoes a transition to a metallic intermediate valence state at 6.5 kbar. Europium sulfide (EuS) is a ferromagnetic semiconductor with a Curie temperature of 16K and

Updated Results of a Solid-State Sensor Irradiation Study for ILC Extreme Forward Calorimetry

Autor: Courcoubetis, George, Crockett, Wyatt, Fadeyev, Vitaliy, Fink, Caleb, Guillemaud, Nikolas, Renteria, Cesar Gonzalez, Gruey, Benjamin, LaBarre, Patrick, Martinez-McKinney, Forest, Rischbieter, Greg, Schumm, Bruce A., Spencer, Edwin, Wilder, Max

Detectors proposed for the International Linear Collider (ILC) incorporate a tungsten sampling calorimeter (`BeamCal') intended to reconstruct showers of electrons, positrons and photons that emerge from the interaction point of the collider with ang
