It is simultaneously a candidate \u003c\/span\u003e\u003cstrong\u003emagnetically\/compositionally tunable topological insulator\u003c\/strong\u003e\u003cspan\u003e and a \u003c\/span\u003e\u003cstrong\u003ephase-change material\u003c\/strong\u003e\u003cspan\u003e, with its topological surface states and reversible amorphous-crystalline switching both of interest.
