Soft x-ray magnetic circular dichroism study of Ca_1-xSr_xRuO_3 across the ferromagnetic quantum phase transition (2007)

Okamoto, J., Okane, T., Saitoh, Y., Terai, K., Muramatsu, Y., ...

Ca_1-xSr_xRuO_3, which is ferromagnetic for Sr concentration x > 0.3, has been studied by x-ray magnetic circular dichroism (XMCD) in Ru 3p and O 1s core-level x-ray absorption. XMCD signals appear...

Soft x-ray magnetic circular dichroism study of weakly ferromagnetic Zn$_{1-x}$V$_x$O thin film (2006)

Ishida, Y., Hwang, J. I., Kobayashi, M., Takeda, Y., Mamiya, K., Okamoto, J., ...

We performed a soft x-ray magnetic circular dichroism (XMCD) study of a Zn$_{1-x}$V$_x$O thin film which showed small ferromagnetic moment. Field and temperature dependences of V 2$p$ XMCD signals...

Indication of intrinsic room-temperature ferromagnetism in Ti1-xCoxO2-d thin film: An x-ray magnetic circular dichroism study (2006)

Mamiya, K., Koide, T., Fujimori, A., Tokano, H., Manaka, H., Tanaka, A., ...

Soft x-ray magnetic circular dichroism (XMCD) measurements at the Co L2,3 edges of Co doped rutile TiO2 at room temperature have revealed clear multiplet features characteristic of ferromagnetic Co2+...

Characterization of Magnetic Components in the Diluted Magnetic Semiconductor Zn$_{1-x}$Co$_x$O by X-ray Magnetic Circular Dichroism (2005)

Kobayashi, M., Ishida, Y., Hwang, J. L., Mizokawa, T., Fujimori, A., Mamiya, K., ...

We report on the results of x-ray absorption (XAS), x-ray magnetic circular dichroism (XMCD), and photoemission experiments on {\it n}-type Zn$_{1-x}$Co$_x$O ($x=0.05$) thin film, which shows...

High-energy spectroscopic study of the III-V nitride-based diluted magnetic semiconductor Ga$_{1-x}$Mn$_{x}$N (2005)

Hwang, J. I., Ishida, Y., Kobayashi, M., Hirata, H., Takubo, K., Mizokawa, T., ...

We have studied the electronic structure of the diluted magnetic semiconductor Ga$_{1-x}$Mn$_{x}$N ($x$ = 0.0, 0.02 and 0.042) grown on Sn-doped $n$-type GaN using photoemission and soft x-ray...

Metal-insulator Crossover Behavior at the Surface of NiS_2 (2003)

Sarma, D. D., Krishnakumar, S. R., Weschke, E., Schussler-Langeheine, C., Mazumdar, Chandan, Kilian, L., ...

We have performed a detailed high-resolution electron spectroscopic investigation of NiS$_2$ and related Se-substituted compounds NiS$_{2-x}$Se$_x$, which are known to be gapped insulators in the...
