Times Cited Count：2 Percentile：37.82(Chemistry, Physical)Hydrostatic and chemical pressure are efficient stimuli to alter the crystal structure and are commonly used for tuning electronic and magnetic properties in materials science. However, chemical pressure is difficult to quantify and a clear correspondence between these two types of pressure is still lacking. Here, we study intermetallic candidates for a permanent magnet with a negative thermal expansion (NTE). Based on in situ synchrotron X-ray diffraction, negative chemical pressure is revealed in HoFe on Al doping and quantitatively evaluated by using temperature and pressure dependence of unit cell volume. A combination of magnetization and neutron diffraction measurements also allowed one to compare the effect of chemical pressure on magnetic ordering with that of hydrostatic pressure. Intriguingly, pressure can be used to control suppression and enhancement of NTE. Electronic structure calculations indicate that pressure affected the top of the majority band with respect to the Fermi level, which has implications for the magnetic stability, which in turn plays a critical role in modulating magnetism and NTE. This work presents a good example of understanding the effect of pressure and utilizing it to control properties of functional materials.

Nilsson orbits have been identified. The total Routhian surface calculations indicate that the transitional nucleus Pt is very soft with respect to 
and deformations. The band properties have been compared with the systematics observed in neiboring nuclei and have been interpreted within the framework of the cranked shell model.

Times Cited Count：2 Percentile：20.91(Physics, Nuclear)Excited states in Tl have been studied experimentally by in-beam -ray spectroscopy. A rotational band built on the configuration with oblate deformation has been established for Tl. Based on the structure systematics of the oblate bands in heavier odd-odd Tl nuclei, we have tentatively proposed spin values for the new band in Tl. The new oblate band shows low-spin signature inversion, and it can be interpreted qualitatively by the two-quasiparticle plus rotor model including a 
-dependent 
-
residual interaction.
