Samples of ZnxMg1-xFe2O4 mixed ferrites are prepared by slightly diffe
rent sintering conditions than in previous reports. X-ray and thermal
diffusivity characterisations are done. The a.c. magnetic susceptibili
ty and hystereses studies show that the samples are ferrimagnetic with
multidomain grains. (C) 1998 Elsevier Science B.V. All rights reserve
