Study of magnetic susceptibility & lattice parameters of CeNiInHx systems

Abstract In the present work we report the study of magnetic susceptibility and lattice parameter measurements of CeNiInH x system with x= 0.0, 0.5, 0.6, 0.67, 0.75, 1.0 and 1.6. It has been revealed that the occurence of paired arrangement of proton in the host material is associated with the electronic phase change of CeNiIn system accompanied with a drastic change in the lattice parameters.

Low temperature magnetic phase of KMnFeF6 : A neutron depolarisation and diffraction study

Abstract Neutron diffraction and zero-field-cooled, field-cooled neutron depolarisation measurements have been carried out for KMnFeF6 system. Our study does not indicate any feature of spin-glass like transition near 108 K as reported in the literature. On the other hand, results show the presence of long range ferrimagnetic correlation in this geometrically frustrated system. The observed features of a.c. susceptibility, low-field magnetisation and neutron depolarisation measurements have been explained on the basis of thermally activated domain wall movement of ferrimagnetic arrangement of canted spins.
