Abstract
The accurate measurement of the Dzyaloshinskii-Moriya interaction (DMI) in ultrathin ferromagnetic/heavy metal heterostructures was recently shown to require extreme experimental care. In this presentation the current state-of-the-art of measuring interfacial DMI is reviewed, and two of the most popular techniques - non-reciprocity of thermally activated magnetostatic spin wave dispersion and asymmetric bubble domain expansion - are discussed for their reliability and applicability. Furthermore, the large discrepancies observed recently between the two techniques are analyzed, and possible origins are discussed. The presentation aims to achieve a deeper comprehension of the reasons behind the discrepancies and to assess the applicability of various techniques to different heterostructures.
