Crystal Structure and Magnetic Properties of the New Zn1.5Co1.5B7O13Br Boracite

Autor: Escudero, Roberto, Morales, Francisco, Ramirez, Marco A Leyva, Campa-Molina, Jorge, Ulloa-Godinez, S.

New Zn1.5Co1.5B7O13Br boracite crystals were grown by chemical transport reactions in quartz ampoules, at a temperature of 1173 K. The crystal structure was characterized by X-ray diffraction. The crystals present an orthorhombic structure with space
