We report the discovery of resolved magnetically split lines in two chemically peculiar stars, the SrEuCr star HD 92499 and the Bp SiCr star HD 157751. From FEROS spectra, we have measured a mean magnetic field modulus of 8.5 kG for HD 92499 and a mean magnetic field modulus of 6.6 kG for HD 157751. Both stars have small projected rotational velocities: v sin i = 3.0 km s −1 and 8.5 km s −1 , r...

Systematic parameter survey calculations were performed to investigate basic characteristics (burnup reactivity loss, Doppler coefficient, sodium void reactivity , control rod worth , power distribution, transmutation rate, breeding ratio etc.) of an LMFBR core loaded with minor actinide (MA) fuels which contain rare earths (RE) and a}so to establish MA and RE loading method which has no seriou...

We have grown single crystals of YbFe6Ge6 and LuFe6Ge6 and characterized their anisotropic behaviour through low field magnetic susceptibility, field-dependent magnetization, resistivity and heat capacity measurements. The Yb valency is confirmed by LIII XANES measurements. YbFe6Ge6 crystals exhibit a field-dependent, sudden reorientation of the Fe spins at about 63 K, a unique effect in the RF...
