Evidence of The Anomalous Fluctuating Magnetic State by Pressure Driven 4f Valence Change in EuNiGe $_{3}$

K. Chen, C. Luo, Y. Zhao F. Baudelet +5

In rare-earth compounds with valence fluctuation, the proximity of the 4f level to the Fermi energy leads to instabilities of the charge configuration and the magnetic moment. Here…

Nature of the magnetism of iridium in the double perovskite Sr2CoIrO6

S. Agrestini, K. Chen, C. -Y. Kuo +12

We report on our investigation on the magnetism of the iridate double perovskite Sr $_{2}$ CoIrO $_{6}$ , a nominally Ir $^{5 +}$ Van Vleck $J_{e f f} = 0$ system. Using x-ray absorption (XAS) a…

Intermediate valence in single crystalline Yb $_{2}$ Si $_{2}$ Al

W. J. Gannon, K. Chen, M. Sundermann +8

Yb $_{2}$ Si $_{2}$ Al may be a prototype for exploring different aspects of the Shastry-Sutherland lattice, formed by planes of orthogonally coupled Yb ions. Measurements of the magnetic…

Probing the $J_{e f f} = 0$ ground state and the Van Vleck paramagnetism of the Ir $^{5 +}$ ions in the layered Sr $_{2}$ Co $_{0.5}$ Ir $_{0.5}$ O $_{4}$

S. Agrestini, C. -Y. Kuo, K. Chen +11

We report a combined experimental and theoretical x-ray magnetic circular dichroism (XMCD) spectroscopy study at the Ir- $L_{2, 3}$ edges on the Ir $^{5 +}$ ions of the layered hybrid…

Evolution of ground state wave function in CeCoIn $_{5}$ upon Cd or Sn doping

K. Chen, F. Strigari, M. Sundermann +13

We present linear polarization-dependent soft x-ray absorption spectroscopy data at the Ce $M_{4, 5}$ edges of Cd and Sn doped CeCoIn $_{5}$ . The 4 $f$ ground state wave functions have…

Intricacies of the Co $^{3 +}$ spin state in Sr $_{2}$ Co $_{0.5}$ Ir $_{0.5}$ O $_{4}$ : an x-ray absorption and magnetic circular dichroism study

S. Agrestini, C. -Y. Kuo, D. Mikhailova +8

We report on a combined soft x-ray absorption and magnetic circular dichroism (XMCD) study at the Co- $L_{3, 2}$ on the hybrid 3 $d$ /5 $d$ solid state oxide Sr $_{2}$ Co $_{0.5}$ Ir $_{0.5}$ O…
