Magnetic switching in the crystalline organic radical compound HbimDTDA

Systems that exhibit hysteretic effects intrinsically possess memory and are therefore of potential technological interest. Understanding the link between hysteresis and structure is an important theme in materials design. Recently, a remarkable new crystalline organic radical compound HbimDTDA was reported. This material exhibits bistability (i.e. memory) in its properties near room temperature. It represents a new member of a rare class of molecule-based magnets and is the first such system based on a DTDA radical. However, many questions still remain about the nature of its magnetic transition and here we propose the first local probe study of the magnetic switching effect using muSR.
