Anomalous temperature-dependent magnetization in the nearly collinear antiferromagnet YCo
Yunshu Shi, Huibo Cao, Hung-Cheng Wu +17
YCo is a newly discovered antiferromagnetic (AFM) compound with distorted kagome layers. Previous investigations via bulk magnetization measurements suggested a complex non…
Evolution toward Quantum Critical End Point in UGe_2
Hisashi Kotegawa, Valentin Taufour, Dai Aoki +2
We report on Hall resistivity and electrical resistivity measurements under pressure and magnetic field in UGe_2 with ferromagnetic (FM) tricriticality. The Hall resistivity sensit…
Thermodynamic and transport properties of single crystalline RCoGe (R = Y, La-Nd, Sm-Tm)
Tai Kong, Charles E. Cunningham, Valentin Taufour +5
Single crystals of RCoGe (R = Y, La-Nd, Sm-Tm) were grown using a self-flux method and were characterized by room-temperature powder x-ray diffraction; anisotropic, tem…
Multiple metamagnetic transitions in helical antiferromagnet CeVGe
Hanshang Jin, Eun Sang Choi, Hung-Cheng Wu +7
We report on neutron diffraction, magnetoresistance, magnetization, and magnetic torque measurements under high magnetic field in the helical antiferromagnet CeVGe. This compou…
Isotope Effect on Electron-Phonon Interaction in Multiband Superconductor MgB2
Daixiang Mou, Soham Manni, Valentin Taufour +5
We investigate the effect of isotope substitution on the electron-phonon interaction in the multi-band superconductor MgB2 using tunable laser based Angle Resolved Photoemission Sp…
Origin of the spin reorientation transitions in (FeCo)B alloys
Kirill D. Belashchenko, Liqin Ke, Markus Däne +7
Low-temperature measurements of the magnetocrystalline anisotropy energy in (FeCo)B alloys are reported, and the origin of this anisotropy is elucidated usi…
