The High Coercivity Field in Chemically Bonded WSe(2)/MoSe(2) Powder

We studied the magnetic properties of WSe [Formula: see text] /MoSe [Formula: see text] powder. The coercivity field reaches 2600 Oe at 5 K, 4233 Oe at 100 K and 1300 Oe at 300 K. These are the highest values reported for two-dimensional transition metal dichalcogenides. This study is different from...

Sumario:We studied the magnetic properties of WSe [Formula: see text] /MoSe [Formula: see text] powder. The coercivity field reaches 2600 Oe at 5 K, 4233 Oe at 100 K and 1300 Oe at 300 K. These are the highest values reported for two-dimensional transition metal dichalcogenides. This study is different from the widely reported vacancy and zigzag structure-induced ferromagnetism studies. Importantly, a Raman peak red shift was observed, and that supports the chemical bonding at the interface between WSe [Formula: see text] and MoSe [Formula: see text]. The large coercivity field originates from the chemical bonding-induced structural distortion at the interface between WSe [Formula: see text] and MoSe [Formula: see text].
