Аннотация: Single crystal, needle shaped samples of diamagnetically diluted cobalt ludwigite CoMgGaO2BO3 have been grown by the flux method. X-ray diffraction and both dc and ac magnetic measurements are described. The unit cell volume changes significantly with dilution, from 328.31 angstrom(3) for the parent compound Co3O2BO3 to 345.46 angsПоказать полностьюtrom(3) for CoMgGaO2BO3. The magnetic transition temperature is considerably lower for the latter compound (25K against 43K for Co2O2BO3). The dc magnetization temperature dependences are split between the field cooled and zero-field cooled regimes and the ac magnetic susceptibility temperature curves are frequency dependent, which indicates possible spin-glass freezing in the magnetic system.
