Bulk ferromagnetism and large changes in photoluminescence intensity by magnetic field in $\beta$-Ga${}_2$O${}_3$

V. Sridharan, Sangam Banerjee, Manas Sardar +3

In this letter we report observation of room temperature ferromagnetism in bulk Ga${}_2$O${}_3$ . We also observe large (10-60%) increase/decrease in photoluminescence. In the red(700…
