Abstract

Abstract: In this work we present the results on experimental study of magnetic phase transitions in ZnO thin films doped by Mn and Co by using the thermal diffusivity and specific heat measurements. The inverted lambda‐shaped peaks observed in the temperature dependencies of the thermal diffusivity demonstrate the existence of the second order phase transitions in these samples. The magnetic entropy derived from the specific heat gives the number of magnetic ions involved in the magnetic ordering. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
