Magnetic multilayers with perpendicular anisotropy and an interfacial Dzyaloshinskii-Moriya interaction contain chiral domain walls and skyrmions that are promising for applications. Here we measure the temperature dependence of the Dzyaloshinskii-Moriya interaction (DMI) in Pt/CoFeB/Ir and Pt/CoB/Ir multilayers by means of static domain imaging. First, the temperature dependences of saturation magnetization ($M_{\rm{S}}$), exchange stiffness ($A$) and intrinsic perpendicular anisotropy ($K_{\rm{u}}$) are determined. Then the demagnetized domain pattern in each multilayer is imaged by wide-field Kerr microscopy...
