Abstract: | The new misfit layer compound (LaSe)1.14(NbSe2)2 has been synthesized from the elements at 1050- and its structure has been determined by a composite approach. The structure has an alternating stacking sequence of LaSe] and two NbSe2] layers along the c direction. The misfit of the two different layers is occurring along the a direction: a1(LaSe)=6.0191 Å and a2(NbSe2)=3.4372 Å therefore yielding a ratio of 1.751 which is very close to 7/4. An investigation of electrical resistivity was done. The crystal shows superconducting properties at 5.3 K. |
