Аннотация: The single crystal needle shape samples of diamagnetically diluted cobalt ludwigite CoMgGaO 2BO 3 have been grown by the flux method. The results of x-ray diffraction and both dc and ac magnetic measurements are presented. The unit cell volume undergoes a noticable growth under dilution from 328.31 A 3 for the parent compound Co3O Показать полностью2BO 3 to 345.46 A 3 for CoMgGaO 2BO 3. The temperature of magnetic transition is considerably lower for the latter compound (25 K against 43 K for Co 3O 2BO 3). The dc magnetization temperature dependencies undergo the splitting of field cooled and zero-field cooled regimes and the ac magnetic susceptibility temperature dependencies are frequency dependent pointing out a possible spin-glass freezing in the magnetic system. © N.B.
