| Abstract | In this paper, the magnetic properties of p-type $Zn_{1-x}Mn_{x}O$ powders are reported. This are prepared from the decomposition of an oxalate precursor $Zn_{1-x}Mn_{x}C_{2}O_{4}^{.}H_{2}O.$ The oxalate precursor is obtained by coprecipitation of 50 ml of a 0.4mol/L aqueous solution of Zn and Mn acetates and the same volume of a 0.4 mol/L solution of oxalic acid. The mixed solution is stirred for 2h at room temperature. We added $CH_{3}COONH_{4}$ and $In(NO_{3})_{3}^{.}H_{2}O$ as p-type doped source (Zn:N:In=l:3:0.05 mol) to the solution with addition 3h stirring. The precipitate is then washed with distilled water and dried in air. The white powders obtained are then annealed in $N_{2}$ at 500-800 K for 2h and finally turned moss yellow powder samples. The structure of the powder samples are studied by X-ray diffraction (XRD). All the observed lines from the XRD patterns show the ZnO structure without any hint of an impurity phase. With the increase of x, the peak position of $Zn_{1-x}Mn_{x}O$ shifts towards lower angles and the lattice constants a and c increase linearly, which means that the $Mn^{2+}$ replaces well the $Zn^{2+}$ to occupy the 2b crystallographic site. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
