In this paper, we show the linearly polarized hard X-ray core-level photoemission spectroscopy of valence fluctuating system beta-YbAlB4. Interestingly, we observed subtle but distinct linear dichroisms in Yb2+ 3d(5/2) core-level spectra at several angles of beta-YbAlB4. Basically linear dichroism in Yb2+ 3d(5/2) core-level spectrum is not expected in the ionic picture because Yb2+ 4f orbital is fully occupied. These contradiction indicates the breakdown of ionic picture in beta-YbAlB4.

We report the core-level photoemission study of cubic PrBe13, PrIr2Zn20 and PrB6 using linearly polarized hard X-ray. We have successfully observed linear dichroism (LD) in Pr3+ 3d core-level photoemission spectra reflecting the 4f ground-state symmetry for all the compounds. The observed LDs and polarization-dependent spectra are reproduced by ionic-model calculations including the full multiplet theory and the local crystalline electric field (CEF) splitting. We have confirmed that LDs in Pr3+ 3d core-level photoemission spectra are able to determine unambiguously the Pr3+ 4f ground-state symmetry.

© 2020 Trans Tech Publications Ltd, Switzerland. We have studied the magneto-transport properties in LMO thin films on a- SiO2 substrates produced by the metal organic decomposition (MOD) method. LMO thin films have been prepared by the MOD method in the 100% O2 gas atmosphere on different heat treatment conditions. Although LMO single crystal is an antiferromagnetic insulator, LMO thin films we have produced in the 100% O2 gas atmosphere by use of the MOD method shows the ferromagnetic metal properties for suitable heat treatment conditions. We consider that the excess of O2- ions in LMO thin films produced in the 100% O2 gas atmosphere induces the strong hole self-doping into those and changes to ferromagnetic metal. The quantity of excess O2- ions in LMO is sensitive to the heat treatment conditions of the LMO production, especially the temperature, time and atmosphere gas. We have obtained the coercive forces from the magnetic field dependence of magnetoresistance. Based on the temperature dependence of the coercive forces, we have estimated the Curie temperature of LMO thin films.
