Abstract

RP-type of phases with the general composition A B O form a well known class of materials exhibiting interesting n+1 n 3n+1 structural and electric transport properties. In the present study a new phase in this class of materials with the composition La NaMn O has been synthesized in the solid state. Study of its crystal structure shows that it crystallizes 3 3 10 in a tetragonal unit cell in the space group I4/mmm. Its structural parameters have been calculated and unit cell structure drawn. Its electrical resistivity in the temperature range 10-300 K shows that it is insulator in nature and ionic conduction plays major part due to the presence of Na ion in the structure.

Keywords: RP-type Phase, La NaMn O , X-ray Diffraction, Electrical Resistance, Insulator
